CRAN has a significant update to rms.  Windows and unix/linux versions 
are available and I expect the Mac version to be available soon. 
The most significant improvement is addition of latex=TRUE 
arguments to model fitting print methods, made especially for use 
with Sweave.

Here is a summary of changes since the previous version.

Changes in version 3.1-0 (2010-09-12)
    * Fixed gIndex to not use scale for labeling unless character
    * Changed default na.action in Gls to na.omit and added a note in 
the help file that na.delete does not work with Gls
    * Added terms component to Gls fit object (latex was not working)
    * Added examples in robcov help file testing sandwich covariance 
    * Added reference related to the effects package under help file 
for plot.Predict
    * Added more examples and simulations to gIndex
    * Fixed ancient bug in lrm.fit Fortran code to handle case where 
initial estimates are nearly perfect (was trying to step halve); 
thanks: Dan Hogan
    * Changed survdiffplot to use gray(.85) for bands instead of 
    * Fixed formatting problem in print.psm
    * Added prStats and reVector functions to rmsMisc.s
    * Changed formatting of all print.* functions for model fits to use 
new prStats function
    * Added latex=TRUE option to all model fit print methods; requires 
LaTeX package needspace
    * Re-wrote printing routines to make use of more general model
    * Removed long and scale options from cph printing-related routines
    * Prepare for version 2.36-1 of survival package by adding 
censor=FALSE argument to survfit.coxph
    * Added type="ccterms" to various predict methods
    * Made type="ccterms" the default for partial g-indexes in gIndex, 
i.e., combine all indirectly related (through interactions) terms
    * Added Spiegelhalter calibration test to val.prob
    * Added a check in cph to trigger an error if strata() is used in 
    * Fixed drawing of polygon for shaded confidence bands for 
survplot.survfit (thanks to Patrick Breheny <patrick.breheny at uky.edu>)
    * Changed default adjust.subtitle in bplot to depend on ref.zero, 
thanks to David Winsemius <dwinsemius at comcast.net>
    * Used a namespace and simplified referenced to a few survival 
package functions that survival actually exports
