2023 Dec 4 4.1-23 Need to remember to build with --compact-vignettes=both 2023 Dec 2 4.1-22 update C code to meet new CRAN standards 2023 Oct 09 4.1-21 update R code to meet new CRAN standards 2022 Oct 20 4.1-18 update C code to meet new CRAN standards update French translation zzzz zzz zz 4.1-17 plot.rpart() gained three new arguments (branch.col, branch.lty, branch.lwd) controlling the color, line type, and width of the branches. 2019 May 21 4.1-16 Updated rpart.matrix to use lapply instead of a loop 2019 Apr 11 4.1-15 Update saved test/example results because of changes to R random number generators 2018 Jul 31 4.1-14 Change post.rpart.Rd example so as to not write outside tempdir() Changed name of solder to solder.balance and added in solder from the survival package (larger than solder.balance). Now data matches between the packages. Modified vignettes slightly 2018 Jan 08 4.1-12 Merge ChangeLog files 2017 Mar 12 4.1-11 Include directly-needed headers, update o/p for R 3.4.0. 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 below 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.

F -> FALSE, T -> TRUE R/labels.rpart.s replace call to prlabel by S code. R/model.frame.rpart.s deparse calls R/na.rpart.s as x has no attributes in R, redesign R/plot.rpart.s change frame=0 to .GlobalEnv R/post.rpart.s change `title' trickery R/print.rpart.s remove nsmall in call to format attr(x, 'ylevels') not 'ylevel' R/rpart.branch.s get with inherits not frame=0 R/rpart.matrix.s adjust for different terms structure R/rpart.s single -> double sys.parent() -> sys.frame(sys.parent()) R/rpartco.s remove frame=0 several times R/snip.rpart.mouse.s drop frame=0 R/summary.rpart.s remove justify="left" in format remove comma in paste(... ,,collapse ...) attr(x, 'ylevels') not 'ylevel' R/text.rpart.s text.default prints "NA", so remove these remove density=0 in calls to polygon R/xpred.rpart.s single -> double sys.parent() -> sys.frame(sys.parent()) R/zzz.R a few missing functions. ------------------- Former file ChangeLog.TMT ------------------- The changes documented since 3/2002, which is the date stated in Brian's version of the Description file. In Sept 2012 the current R version and the Mayo version were merged. 14March02: When y was a factor, with no instances of one of the levels in the "middle" of the levels list, the program would generate NA due to division by 0. Fairly simple fixes to gini.c and rpart.s. The bug, and a very nicely documented test case, was supplied by Matthew Wiener. 8Aug02: Small bug pointed out by Kai Yu in rundown.c - a missing pair of {}, which only apply if usesurrogate < 2 and there are lots of missings. Appears that the se of the xval error would be too small. 29Oct02: Error in xpred.rpart.s, for a user split with a response vector >1, the "yback" vector was too short. (Diff the lines creating eframe with those of rpart.s, to see the obvious oversight!) Leads to a core dump. 29Oct02: Fix error in branch.c, which was not watching out for missing values in the surrogate variable. Found due to close reading of the C code by Kai Yu. (I'm impressed!) 12Nov02: Add the "return.all" argument to xpred.rpart, to fit the needs of Dan Schaid. Add the test case xpred.s to test it. 28Nov02: Major changes to how indexing is done. In the older version, at a lower branch on the tree one would find the following code again and again: for (i=0; i
