rattle 5.3.6

• Bug fixes: predict for xgboost; ignore NA in checking for binary class; varImp log handling.

rattle 5.3.1

• Convert datasets to be tibbles, moving towards tidyverse compliant. Require tibble package. Also require bitops as needed when loading a tibble as an RDataset into Rattle.

rattle 5.3.0 (2019-12-16)

• Cleanup and prepare for CRAN release.

rattle 5.2.8

• Remove dependencies on archived packages RGtk2Extras and playwith.
• Bug fix View Data button to just call R's View() rather than a glade data view or RGtk2Extras data viewer.
• Update weatherAUS dataset with most recent weather observations now with 166,310 data points.

rattle 5.2.7

• Bug fix - the export PMML file dialog stopped working - perhaps a RGtk2 update. It was using glade. Instead create the dialog directly in code. Reported by Julian Ochoa.

rattle 5.2.6

• Bug fix - rattle was incorrectly specifying load instead of open in a GTK file chooser which did not work on an RGtk2 update. Reported by Dave Arnold and Eric Mattys.

rattle 5.2.5

• Add labels to var imp plot for conditional forest.

rattle 5.2.4

• Bug fix in getCategoricVariables() when no target is defined and include.target is true.
• Bug fix in kmeans stats when the data is scaled. Reported by Caleb Terrel Orellana.

rattle 5.2.3

• Bug fix random forest Errors and OOB ROC buttons are not available for conditional random forests. Reported by Cristina Acasuso.

rattle 5.2.1

• Improve handling of Missing RGtk2 message.
• Bug fix re default maxdepth in rpart tree. Reported by Eugene Dubassarsky.

rattle 5.2.0 (2018-08-17)

• Remove dependency on RGtk2 and check it dynamically. Rattle has more functionality than just the GUI yet we force installation of RGtk2 which is problematic on some platforms.
• Return the datasets to rattle package. Has caused too much confusion as a separate package.

rattle 5.1.6

• Bug fix for new rpart.plot with roundint= handled automatically.
• Reduce width of bars in ggVarImp() plot.

rattle 5.1.5

• Remove deprecated connect-r logo. Reported by Bob Muenchen.

rattle 5.1.0 (2017-09-05)

• Resolve all final check tests, redo testing, and release to CRAN.

rattle 5.0.19

• Debug the xgboost interface - limited to binary classifcation tasks for now. Key is that the R code is exported and can be used as a template for extended modelling.

rattle 5.0.18

• Tune Boost interface.

rattle 5.0.17

• Move the dataset from the rattle package to a separate rattle.data package in line with CRAN guidelines to have a separate package for slower changing datasets of considerable size. This will also allow the option to provide further datasets for rattle as part of that package.
• Use weather.csv as the sample for both R and Microsoft R as weatherAUS.csv is too large to include in a CRAN package.
• Ensure strings are treated as categoricals on loading the data with Microsoft R so as to conform to read.csv() and to be consistent with the non-Microsoft R version of Rattle.

rattle 5.0.16

• Update the weather dataset from the Australian Bureau of Meteorology and add sample weatherAUS.xdf to the package to be loaded as the default example when Microsoft R is detected. XDF is a file system based data format used by Microsoft R to handle datasets of *any* size rather than being limited by available computer RAM.

rattle 5.0.15

• Merge RevoScaleR (Microsoft R) support for NeuralNetworks and KMeans from Microsoft India Data Group team.

rattle 5.0.14

• Merge support for RGtk2 2.20.31 and 2.20.33 to resolve the bug across all installations.

• Bug fix call to errorMatrix() where counts= is not count=.
• Bug fix to evaluate where respcmd for random forest has disappeared when incorporating MRS updates.

rattle 5.0.11

• RGtk2 version 2.20.33 released and caused some issues with Rattle. Heuristic test of libglade/GtkBuilder began failing and retval no longer used for obtaining returned values.

• Remove macosx special rattle.ui. The ubuntu specific text no longer appears in the saved ui file.
• Internally: Move rattleGUI to crv from crs. The crs is saved as the state, and this was confusing the GUI on a project restore. Had to ensure we restored rattleGUI with the current rattleGUI - this fixes loadProject bug. Also, in Load project, filter on .RData not .Rdata.
• Add newdata= to call to predict, in line with the standard approach by party (reference Torston). Remove the OOB= for predict for cforest. With a new dataset OOB makes no sense. It was in there because newdata= was not being used and positionally having issues.
• Update fancy rpart plot to reduce colour intensity for printing and a nicer tree structure. Add all class probs to fancy tree.
• Define paste0 if it is not defined. It was introduced in 2.15.0 but is too early to assume the world is with us.

Another was code copied from the Internet from David Hand - use the Hmeasure package now. Note in drawTreeNode() reference to the original author and lack of copyright. Note author in Authors@R. ggcorplot is now available from Deducer. Remove it from Rattle. Replace Hand measure with HMeasure from hmeasure. Add Mark Vere Culp as aux author. Remove commented out code. Remove lss and cranSearch - not really part of Rattle.

• Add rattle.ui to the google code repository.
• Remove as many literals as possible from the Log tab - so that crs$dataset[crs$sample, c(2:10,14,16:20)] becomes crs$dataset[crs$sample, c(crs$input, crs$target)], for example. Similarly for the set.seed and other data storing variables.
• Other Log tab cleanup.
• Fix bug that caused failure on reading an .xls data file.

• On adding to the log when saving a plot make sure carioDevice is loaded and the file name path separators are appropriate. Reported by Shane Butler 11 Dec 2010.
• Ensure filename string is UTF-8 when exporting a file, to handle Japanese filenames.
• For nnet, choose a seed so weather generates a non-trivial model.
• Refer to remapping as recoding in line with commonly used terminology.
• Default back to showing text on icon for buttons. Seems okay in the new version of Gtk. -- Graham Williams <[email protected]> Sat, 11 Dec 2010 13:39:55 +1100 rattle (2.5.47) unstable; urgency=low
• Add a useGtkBuilder argument to rattle(). If NULL, then heuristically determine, otherwise go with the specified choice, if possible.
• Remove RGtk2, colorspace, and pmml as dependencies. Now dynamically check and offer to install. This also helps reduce chance of the XML/RGtk2 zlib1.dll bug, and also ensure RGtk2 loads before XML to avoid that bug. -- Graham Williams <[email protected]> Mon, 15 Nov 2010 21:50:15 +1100 rattle (2.5.46) unstable; urgency=low
• Bug fix for fixTranslations.
• Save weights information in PMML.
• Cleanup SVM command generator. -- Graham Williams <[email protected]> Thu, 11 Nov 2010 19:08:36 +1100 rattle (2.5.45) unstable; urgency=low
• Check for GtkBuilder handling of the 'requires' tag, and if not handled the don't use GtkBuilder.
• Bump pmml version through 1.2.25 to 1.2.26.
• Change default nolan groups for a singularity to 50 rather than 99.
• PMML bug fix when glm and using weights.
• Move all variable initialisation from .onLoad to .onAttach. This will ensure .RData saved (and therefore old) versions of the variables will not overwrite the proper versions in a newer release of Rattle. -- Graham Williams <[email protected]> Sat, 09 Oct 2010 08:16:15 +1100 rattle (2.5.44) unstable; urgency=low
• Add an include.libpath to rattle.info() to provide information about where the packages are installed.
• Check for failed startup of rattle GUI using GtkBuider (because the Gtk library installed does not recognise 'requires' and suggest a workaround).
• Condiionally turn toolbar Text (in addition to just Icons) on.
• For loading spreadsheets, make sure RODBC is available and loaded.
• Ensure 'ordered categoric' are treated as categoric for Explore, Distribution. -- Graham Williams <[email protected]> Tue, 05 Oct 2010 18:08:20 +1100 rattle (2.5.43) unstable; urgency=low
• Ensure gtkBuilder is setting the correct translation domain for the interface.
• Add global option for not showing timestamps: crv$show.timestamp.
• Add optional arg to newProject to not ask about overwriting a project. Default is as previously - to ask. -- Graham Williams <[email protected]> Wed, 22 Sep 2010 05:37:53 +1000 rattle (2.5.42) unstable; urgency=low
• Update rattle.info() to recursively identify all dependencies, report their version number and any updates available from CRAN and generate command to update packages that have updates available. See ?rattle.info for the options.
• Fix bug causing R Dataset option of the Evaluate window to always revert to the first named dataset.
• Fix bug in transforms where weights were not being handled in refreshing of the Data tab.
• Fix a bug in box plots when trying to label outliers when there aren't any. -- Graham Williams <[email protected]> Sun, 19 Sep 2010 05:01:51 +1000 rattle (2.5.41) unstable; urgency=low
• Use GtkBuilder for Export dialog.
• Test use of glade vs GtkBuilder on multiple platforms.
• Rename rattle.info to rattle.version.
• Add weight column to data tab.
• Support weights for nnet, multinom, survival.
• Add weights information to PMML as a PMML Extension.
• Ensure GtkFrame is available as a data type whilst waiting for updated RGtk2.
• Bug fix to packageIsAvailable not reruning any result.
• Replace destroy with withdraw for plot window as the former has started crashing R.
• Improve Log formatting for various model build commands.
• Be sure to include the car package for Anova for multinom models.
• Release pmml 1.2.24: Bug fix glm binomial regression - note as classification model. -- Graham Williams <[email protected]> Wed, 15 Sep 2010 14:56:09 +1000 rattle (2.5.40) unstable; urgency=low
• Conditionalise useGtkBuilder: if windows and R before 2.12.0 then libglade if unix and R 2.12.0 then libglade for now (RGtk2 update needed?) all else use GtkBuilder -- Graham Williams <[email protected]> Sun, 22 Aug 2010 12:02:00 +1000 rattle (2.5.39) unstable; urgency=low
• Conditionally use either libglade2 or GtkBuilder for the GUI. libglade2 (a separate library to the Gtk+ library) is deprecated and as of R 2.12.0 won't be supported on MS/Windows binary builds. The default is now GtkBuilder (built into the Gtk+ library), and support for libglade2 within Rattle is deprecated. RGtk2 (2.12.18) still has issues in its support of GtkBuilder and is being actively worked on, but Rattle is currently working around these. -- Graham Williams <[email protected]> Sat, 21 Aug 2010 07:47:43 +1000 rattle (2.5.38) unstable; urgency=low
• Ensure pmml.ksvm will at least run - though resulting PMML not validated.
• Bump pmml version to 1.2.23 -- Graham Williams <[email protected]> Fri, 06 Aug 2010 05:56:11 +1000 rattle (2.5.37) unstable; urgency=low
• The Predictive tab has gone back to being Model. Not sure which is best.
• cranSearch defaults to r-project rather than unimelb.
• Migrate from RGtk2DfEdit to its replacement, RGtk2Extras.
• Revert cairoDevice to being a Suggests rater than Depends.
• Remove redundant CITATION from root of package, as the real one is in inst. -- Graham Williams <[email protected]> Sat, 31 Jul 2010 14:34:50 +1000 rattle (2.5.36) unstable; urgency=low
• Add Bill Venables' searchCRAN example code.
• Improve error message when we find duplicate variable names in a loaded file, which might result when there is no header line.
• Add help item for Projects.
• On Evaluate with supplied file, use the hdr specified on the Data tab. -- Graham Williams <[email protected]> Mon, 12 Jul 2010 06:43:06 +1000 rattle (2.5.35) unstable; urgency=low
• Add utility lss function to list object sizes.
• Add options text entry for SVM to easily allow other options.
• Better formatting of the Log tab.
• Use a set.seed for SVM to ensure same model each time.
• Add option to random forest to impute missing values rather than simply ignoring the observations.
• On Evalaute with supplied file, use the sep specified on the Data tab, thus allowing TXT files.
• On loading a new dataset for evaluation be sure to add in any missing columns, and unify the levels.
• Improve binning documentation.
• Make RGtk2, cairoDevice, colorspace all dependencies so we can get rattle started and then rattle will prompt to install other packages that are mssing when it needs them. -- Graham Williams <[email protected]> Thu, 01 Jul 2010 15:34:50 +1000 rattle (2.5.34) unstable; urgency=low
• When a package is missing, there is now the option to install it right then, and it continues as normal after it gets installed.
• Change Suggests to Depends so all used pacakges get loaded on loading rattle, in an attempt to make it easier to install Rattle. Then the r-cran-rattle package on Debian/Ubuntu will have all required dependencies and a normal install.packages will get all dependencies also, rather than having to use dependencies=c('Depends', 'Suggests'). Penalty is it takes 20 seconds to do 'library(rattle)' on a server and 90 seconds on a netbook - so revert back to not doing this.
• Ensure the new train/validate/test scneario is saved across projects. -- Graham Williams <[email protected]> Wed, 09 Jun 2010 07:04:08 +1000 rattle (2.5.33) unstable; urgency=low
• Bug fix rf.cmd.
• Improve scoring functionality: The dataset can have NA's for target, and these can now get scored by rf on Evaluate tab. Loading a CSV file to be scored no longer needs to have the target column included (previously it needed to be there and have non-NA values). Thanks to Chris Snijders. -- Graham Williams <[email protected]> Mon, 31 May 2010 06:22:54 +1000 rattle (2.5.32) unstable; urgency=low
• Remove dependency on car - not actually being used at the moment.
• For random forest, allow sample size text entry as a single integer or a list, as per randomForest.
• Use na.omit with cforest, as is done with randomForest.
• For randomForest turn subsampling with replacement off since it is more likely to produce biased importance measures, as explained in by the cforest papers.
• Fix bug with multiple "contact support" lines in error popups.
• When showing the randomForest importance values, sort on the accuracy measure rather than the Gini measure, since the Gini is biased in favour of categoric variables with many categories.
• ada boost seed should be 42, like all other seeds.
• Tidy up some ada output.
• Bug fix - save project for rf failing (looking for rf_sampsize_entry).
• Remove text from toolbar by default.
• Change order of Forest/Boost buttons on Model tab.
• Add tooltips for all toolbar buttons. -- Graham Williams <[email protected]> Fri, 28 May 2010 15:47:15 +1000 rattle (2.5.31) stable; urgency=low
• Add rattle.info() to list information for debugging purposes.
• Bump pmml to 1.2.22
• Fixes from [email protected]: Extension in Header should be first element. Coefficients in regression models should not be NA (as will be for singularities), but replace with, and so no impact of change.
• Ensure Survival defaults are reset appropriately. -- Graham Williams <[email protected]> Wed, 19 May 2010 09:50:39 +1000 rattle (2.5.30) stable; urgency=low
• On MS/Windows with Japanese, read.csv needs encoding option set with file rather than with read.csv (for UTF-8) but seems okay under other scenarios.
• On MS/Windows with Japanese (UTF-8) the encoding of the variables selected for transforming needs to be UTF-8 for much of the process, but "unknown" when using Rtxt and sprintf (when substituting the variable names) to ensure resulting message is correctly matched for encodings. -- Graham Williams <[email protected]> Wed, 19 May 2010 09:47:12 +1000 rattle (2.5.29) stable; urgency=low
• Add the translation file.
• Fix an Encoding/sprintf issue for Japanese on MS/Windows.
• Allow crv$NOTEBOOK.MODEL.NAME to be overridden by other packages (RStat).
• When dispatch fails be sure to include the Tab label on which it fails.
• Ensure HClust Options are re-enabled on loading a project. -- Graham Williams <[email protected]> Sat, 24 Apr 2010 07:32:02 +1000 rattle (2.5.28) stable; urgency=low
• Minor format changes for glm and rf model output.
• Capture additional survival model error and suggest a solution.
• Remove spurious additional plot for Survival Residual plot.
• Update log tab labels to be more generic.
• Update tooltips to be generic and add survival tooltips. -- Graham Williams <[email protected]> Thu, 22 Apr 2010 06:21:58 +1000 rattle (2.5.27) unstable; urgency=low
• Further translation fixes. In particular, use Encoding(...getText()) <- "UTF-8" to ensure strings from the GUI ate UTF-8, and not unknown.
• Ensure training dataset rather than sample dataset nomenclature is now used.
• Ensure execute button can only be clicked once while it is processing.
• Survival plot buttons need to be made sensitive as appropriate.
• For Japanese on MS/Windows do not use monospace font since this ends up vertically cenbtering periods and commas (and all other characters). Need a fixed width font that does not do this, but for now we put up with variable width font.
• Revert to using only English for all hidden tab labels.
• Improved identification of current plot number.
• Bug fix multiple vars selected for asnumeric and ascategoric transforms. -- Graham Williams <[email protected]> Thu, 22 Apr 2010 06:17:20 +1000 rattle (2.5.26) unstable; urgency=low
• Add Cross Tab option to Explore tab to generate cross tabulations of each categoric variable by the target variable. (Luke Lake)
• Bug fix - improve how we obtain the plot number from the title, particularly in the context of translations.
• Further translation markup.
• Clean up the use of dfedit.
• Minor improvement to spacing in Log tab. -- Graham Williams <[email protected]> Tue, 30 Mar 2010 21:37:29 +1100 rattle (2.5.25) unstable; urgency=low
• Start using the RGtk2DfEdit for the View and Edit buttons of the Data tab, and the Enter/Score option of the Evaluate tab. RGtk2DfEdit provides a spreadhseet like interface to the data. Various data editing options are available. Also press = to run an arbitrary R command on selected data (e.g. select two columns of data and issue the plot command).
• Add further markup of text for translations.
• Support specification of the character used for decimal points (to suit some European usage).
• Fix bug in exporting XML - replace & with &amp;
• Survival plots - split survival chart plot from residuals plots, and plot all residuals.
• Fix logic behind what is greyed out in the Test tab. -- Graham Williams <[email protected]> Mon, 29 Mar 2010 19:37:25 +1100 rattle (2.5.24) stable; urgency=low
• Revamp the help text, and put into the Rtxt translation framework.
• Fix the height of the data name widget (the library option was growing the width for some reason).
• For Evaluate, add Full and Enter as dataset options. Enter will pop up an editor with the final row from the dataset, allowing you to add rows or modify the supplied row. We supply the row so that we have an example to work from. Full uses the whole original dataset. -- Graham Williams <[email protected]> Sat, 06 Mar 2010 14:17:12 +1100 rattle (2.5.23) stable; urgency=low
• Catch "arules" error in converting data to transactions when baskets contain repeated items.
• When data tab is executed, and so crs$rpart is reset to NULL, always remove the Draw/Rules button from the Tree option of the Predictive tab.
• Add code to fix translations that are not being loaded when using RGtk2 on MS/Windows. All is okay on GNU/Linux, but RGtk2 seems not to get the right locale for loaded Glade file. The fix is to traverse the GUI and change all labels, on starting up Rattle. RGtk2 authors tried to fix but it remains an issue.
• Ensure rpart is reset on resetting rattle.
• Rework handling of tab pages because a Japanese translation on MS/Windows is having issues with the following call (nd=notebook) nb$getTabLabelText(nb$getNthPage(nb$getCurrentPage())) returning what looks like Shift-JIS encoding of the string rather than UTF-8, and hence not string matching the expected tab label.
• Fix spelling errors on help menu and ensure help for all topics is covered.
• For nnet, use MaxNWts=10000 (default is 1000) to allow larger nets by default, and capture the error message when this is exceeded and better explain what to do.
• Ensure we don't export an empty dataset when choosing export on the data tab.
• Capture arules error message when there are repeated items in one basket, and explain this more clearly.
• For rpart use information as the default split rather than Gini - makes little if any difference.
• Allow showHelpPlus to have an extra/alternative question that is displayed.
• All random seeds should be 42.
• Reset kmeans tab on loading a project.
• Add dozen more weather stations to the weatherAUS dataset.
• Improve the logic for the display of the Report radio buttons on the Evaluate tab.
• Spelling correction to a number of tooltips. -- Graham Williams <[email protected]> Wed, 03 Mar 2010 06:50:58 +1100 rattle (2.5.22) stable; urgency=low
• Default window height is 650, but not forced so that the window nicely fills a netbook screen if maximised.
• Bump R dependency to 2.8.0 in line with update of the CITATION file. -- Graham Williams <[email protected]> Sat, 13 Feb 2010 09:48:00 +1100 rattle (2.5.21) stable; urgency=low
• Re-enable gettext on MS/Windows, even though RGtk2 2.12.18 has not fixed the bindtextdomain problem with glade files and package supplied translations.
• Change the tree plot to us "< =>" and ">= <" to clearly identify which branch the "=" results go. Could not figure out how to get expression to us a "ge" symbol.
• Improve formatting of the PvO plots.
• Use the pairs.panels function from the psych package for the default scatterplot on the Explore tab.
• Add INSTALL file. -- Graham Williams <[email protected]> Sun, 07 Feb 2010 15:03:22 +1100 rattle (2.5.20) stable; urgency=low
• Restore missing weather.csv file.
• Add to Google code: weather.R ChangeLog NEWS ToDo upload_uwe.sh upload_cran.sh. -- Graham Williams <[email protected]> Sun, 31 Jan 2010 11:07:55 +1100 rattle (2.5.19) unstable; urgency=low
• Ensure the right labels (Time/Risk rather than Class/Prob) displayed in filechooser when exporting a survival model.
• Model tab renamed as Predictive.
• Ensure boxplots have same "by ..." in the main title.
• Update the weather dataset and include many more weather stations in the weatherAUS dataset.
• Rtxt does no translations when running on MS/Windows (for now). -- Graham Williams <[email protected]> Sat, 30 Jan 2010 09:28:18 +1100
