There have been a number of improvements and bug fixes in the rms
package which is now on CRAN for linux/unix (and shortly to be available
for Mac and Windows).
* Gls: Updated optimization calls - had become inconsistent with gls
and failed if > 1 correlation parameter (thanks: Mark Seeto
<markseeto at gmail.com>); removed opmeth argument
* print.fastbw: added argument: estimates
* survplot.survfit: handled fact that survival:::summary.survfit may
not preserve order of strata levels. Also fixed survit.cph and cph;
Thanks: William.Fulp at moffitt.org
* plot.Predict: added example showing how to rename variables in plot
* print(fit object, latex=TRUE): added latex.naprint.delete, used
new Hmisc latexDotchart function to make a dot chart of number of NAs
due to each model variable if at least 4 variables have NAs
* added trans argument to plot.anova.rms to allow transformed scales
* Corrected cph to use model.offset(); thanks: Simon Thornley
<s.thornley at auckland.ac.nz>
* Changed latex.anova.rms to use REGRESSION instead of TOTAL label
* Changed gendata, contrast.rms to allow expand=FALSE to prevent
expand.grid from being called to generate all combinations of predictors
* Added type= to plot.Predict to allow user to specify a different
default line/point type (especially useful when x is categorical)
* Corrected bug in offset in psm - made default offset the length of X
* Corrected bug in calibrate.psm (fixed -> parms)
* predab.resample, calibrate.cph, calibrate.default, calibrate.psm:
stopped putting results from overall initial fit into .Global and
instead had predab.resample put them in attribute keepinfo, obtained
from measure()
