[Frank Harrell]

An update to the rms package is now on CRAN.  Some recent changes:

    * plot.summary.rms: allowed a vector for lwd, and passed lwd to 
confbar.  Thanks: Michael Friendly
    * gendata: Starting in R 3.1.0, as.data.frame.labelled or 
as.data.frame.list quit working when length vary; workaround
    * predictrms, ols: handle offset in formula.  Thanks: Max Gordon
    * pentrace: neatened code, added new argument noaddzero if user 
wants to prevent unpenalized model from being tried; add new test script 
in tests
    * bplot: fixed bug whereby xlabrot was ignored.  Thanks: Sven 
Krackow <sven.krackow at gmail.com>; new test for bplot in tests directory
    * plot.Predict: fixed bug in which 2nd argument to perim was not correct
    * validate.ols: Shane McIntosh fixed the passing of the tolerance 
argument to predab.resample
    * predictrms: computed offset earlier so always defined no matter 
the value of type
    * plot.Predict: added scaletrans argument, fixed use of subscripts 
in pan
    * lrm, lrm.fit: added scale argument
    * orm, orm.fit: added scale argument
    * vcov.orm: accounted for scale when extracting covariance matrix
    * npsurv: was not passing type argument
    * npsurv: start storing all classes created by survfit.formula
    * logLik.Gls: added.  Makes AIC(Gls object) work.
    * NAMESPACE: several changes
