Rattle: To-Do List

This is a brief list of some of the things in the pipeline or suggested by users. Feel free to email me with suggestions and priorities and especially code.

080512 Fix scoring for multiple class classification

080512 Notice $ amounts and , in thousands and treat as numeric (Tony Nolan)
080517 Add a macros menu with canned R templates (Tony Nolan)
080511 Move to using guiDo from plotAndPlayGTK
080511 Move to using playwith from plotAndPlayGTK for plots
080511 Add support for scagnostics package
080504 Allow risk charts without a RISK identified
080502 Put PMML.COPYRIGHT into .Rattle
080502 Add report info to PMML export of GLM
080501 Fix cluster export to CSV
080429 Add a SQLiteDF data option
080427 Report pmml.nnet error to Zementis
080427 Fix Draw of decision tree for Regression
080427 On Score be sure to include the commands in log.
080426 Add "Transform" check button on Evaluate tab (active when Score and CSV)
       that will perform same transformations on the scoring dataset. (Tony)
080427 Fix export of PMML for rpart
080421 For assoc, if ID is not unique, set Baskets to checked
080422 Complete read.pmml function for rpart.
080419 Accumlate the transforms and apply to new CSV score file (Tom Neice)
080418 Change plots to be tabbed plots with second tab being parameters that
       lay behind the model whose performance is being plotted.
080418 Load rattle script files (.ras) for data, score, test:
080418 Allow txt score file (perhaps automatic if training data is txt)
080415 Fix about Quit button
080408 Transform Tab, "Filter" textbox for rows to keep
080330 After Transform refreshes list, keep same selections?
080318 Migrate all global variables into the crv$ structure - avoid warnings
080315 Add a Last Dataset/Project option (Tony Nolan)
080305 Implement silhouette plot for kmeans clusters
080203 Ed Cox: Add row selection to Select Tab (perhaps using "subset").
080203 Ed Cox: Bug when using ODBC data source multiple times.
060921 Pareto, zipf (ginger.hpl.hp.com/shl/papers/ranking/ranking.html) (Stu)
070106 Transform: Implement mean/median from knn imputations (Daniel Medri)
071215 Display rsq.rpart - the r squared fit by splits.
071216 Add date conversion to Remap: as.Date(COLUMN, format="%d-%m-%Y")
071216 Rename binning to not conflict with sm's binning.

071205 Add in Randy Goebel's association rule visualisation (AI07)
071125 Use relaimpo  to calculate relative importance of variables:
       calc.relimp(Adjusted ~ ., audit[,c(2,7,9:10,13)], 
       type = c("lmg", "last", "first", "betasq", "pratt") )
070422 Disable drag and drop from the file open dialogs (Ray Lindsay).
070406 For the cairo plot window, introduce keyboard shortcuts.
070325 Add a Defaults button to each model builder.
070130 Explore->Distr check buttons train/test/csv (csv from Evaluate tab)
070330 Add selection of clustering: diana, agnus, fanny, etc.
070421 Ensure the Help menu is complete.

Notes

The caret package provides a unifying interface to the model builders and cold be used underneath in Rattle. It isn't at present - Rattle uses the source packages to ensure we teach the use of the underlying model builders. As a data miner moves into R they may like to consider the use of the caret package for command line usage. The package also provides a tuning facility.
080118: Considered moving to using the VGAM package for regression. Decide not to move now - VGAM is hijacking S4 classes for predict and other functions. The author is now aware of this. library(VGAM) results in all other models no longer working - no "predict" and pmml.lm fails with no coefficients!
