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:
