directly by users. rms uses generic functions defined in other packages.
For example there is a latex method in the Hmisc package, and rms has a
latex method for objects of class "anova.rms" so there are anova.rms and
latex.anova.rms functions in rms. I use:

Bootstrap BCa confidence limits with your own resamples

Thanks very much,

and bootcov
* Added bootBCa function
* Added seed to bootcov object
* Added boot.type=''bca'' to Predict, contrast.rms, summary.rms
* Improved summary.rms to use t critical values if df.residual defined
* Added simultaneous contrasts to summary.rms
