[R] [R-pkgs] New version of rms package now on CRAN
Version 2.2-0 of the rms package is now available. This is a somewhat major update. One major change is not downward compatible: Instead of specifying predictor=. or predictor=NA to Predict, summary, nomogram, survplot, gendata, you just specify the name of the predictor. For example, to get predictions for the default range of x1 and for just 2 values of x2 you might specify Predict(fit, x1, x2=c(1,3)). The next major change is the use of lattice graphics in bplot, so that now you can easily make multi-panel 3-D displays of effects in the fitted model. The package's web site is http://biostat.mc.vanderbilt.edu/rms Here is what's new: * Added levels.only option to survplot.* to remove variablename= from curve labels * Added digits argument to calibrate.default * Added new ref in val.prob help page * Corrected location of dataset in residuals.lrm help page (thanks frederic.holzwarth at bgc-jena.mpg.de) * Fixed latex.rms to latex-escape percent signs inside value labels * Added scat1d.opts to plot.Predict * Changed method of specifying variables to vary by not requiring an equals sign and a dot after the variable name, for Predict, summary, nomogram, gendata, survplot.rms * Added factors argument to Predict to handle the above for survplot * Made gendata a non-generic function, changed the order of its arguments, removed editor options, relying on R de function always * Thanks to Kevin Thorpe <kevin.thorpe at utoronto.ca> to make latex.summary.rms and latex.anova.rms respect the table.env argument * Fixed bug in calibrate.default related to digits argument * Re-wrote bplot to use lattice graphics (e.g., levelplot contourplot wireframe), allowing for multiple panels for 3-d plots * Changed all Rd files to use {arg1,arg2,...} instead of having empty {} -- Frank E Harrell Jr Professor and Chairman School of Medicine Department of Biostatistics Vanderbilt University _______________________________________________ R-packages mailing list R-packages at r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages
