2016 ??? ?? 4.1-11 Include directly needed headers. 2015 Jun 29 4.1-10 Tweak imports. 2015 Feb 11 4.1-9 Update Korean translations. Remove some unused assignments. 2014 Mar 28 4.1-8 Update Polish translations. 2014 Mar 24 4.1-7 Update French and German translations. Fix array-overrun in gini.c (detected by valgrind checks for adabag). 2014 Mar 07 4.1-6 model.frame() method could fail when the recorded call was rpart::rpart(). 2014 Jan 25 4.1-5 Avoid abbreviation in tests/treble.R More comprehensive Description: field. 2013 Dec 10 4.1-4 Change pre-defined structure sizes to mitigate false positives from Undefined Behaviour Sanitizer. 2013 Sep 01 4.1-3 Document TMT change to predict() output. 2013 Aug 15 4.1-2 Replace calls to as.name(). Remove unused and un-exported rpartpl(). Correct plot.rpart.Rd as to where things are stored. Increase version dependence to >= 2.15.0, remove conditional paste0 from this package. 2013 Mar 20 4.1-1 Add ko translations, update reference output for 3.0.0. 2012 Nov 29 4.1-0 Remove rpconvert() (converted rpart2 trees). Clean up a lot of the R code. C code reformatted with GNU indent and -i4 -nut -ncdb -d1 -br -ce -il0 -npcs -brs then use whitespace-cleanup in Emacs. Call R_CheckUserInterrupts at each phase of cross-validation. Ensure that surrogates really are better than the default split (adj > 1e-10), and that at least 2 cases of non-zero weight go each way. Removed unused file src/s_xpred.c. 2012 Nov 18 4.0-3 Add 'importance' to rpart object and to summary(): from TMT. 'minlength' arg for tree() method. Improved handling of weights with zero fit, including bugfix for ordered factors. free_tree was commented out in rpart.c, and could crash as the structure was not zeroed. As a precaution, pointers which are freed are NULLed. s_xpred.c did not free the first instance of a tree. make_cp_list used calloc but did not free. Spell-check help pages and vignettes. Several examples needed par(xpd = TRUE) at default plotting sizes. 2012 Nov 11 4.0-2 Add car90 dataset from TMT. 'agree' in choose_surg.c needs to be double for fractional weights. Not use paste0() so R 2.14.x works. 2012 Oct 26 4.0-1 Merge in updates from TMT: see inst/NEWS.Rd and Changelog.TMT. Use .Call for all C code. Use an environment in the package for 'parms' from plot.rpart(). Force byte-compilation for consistency. 2012 Oct 03 3.1-55 Force use of registered symbols in R >= 3.0.0 Update Polish translations. Work on message formats. text(fancy = TRUE) gains a 'bg' argument. 2012 Jun 27 3.1-54 Add Polish tranlations. 2012 Jun 01 3.1-53 rpart, rpart.matrix: allow backticks in formulae. tests/backtick.R: regession test 2012 Mar 04 3.1-52 src/xval.c: ensure unused code is not compiled in. 2012 Jan 11 3.1-51 Change description of 'margin' in ?plot.rpart as suggested by Bill Venables. 2011 Apr 09 3.1-50 Change licence to GPL-2 | GPL-3 Remove set-but-unused variable in src/xval.c 2011 Mar 06 3.1-49 Update testall.Rout.save for R 2.13.0 2010 Dec 08 3.1-48 Avoid partial match to args, unnecessary as.vector.
