Punits

Takes a character variable containing units of measurement for a variable.
If it has zero length, a <code>""</code> string is return. Otherwise, any trailing <code>"s"</code> is
removed if the string is longer than one character, and depending on the arguments,
the string is changed to lower case, <code>"s"</code> is added, and the first character is
changed to upper case.

Regression modeling, testing, estimation, validation,
graphics, prediction, and typesetting by storing enhanced model design
attributes in the fit.  'rms' is a collection of functions that
assist with and streamline modeling.  It also contains functions for
binary and ordinal logistic regression models, ordinal models for
continuous Y with a variety of distribution families, and the Buckley-James
multiple regression model for right-censored responses, and implements
penalized maximum likelihood estimation for logistic and ordinary
linear models.  'rms' works with almost any regression model, but it
was especially written to work with binary or ordinal regression
models, Cox regression, accelerated failure time models,
ordinary linear models,	the Buckley-James model, generalized least
squares for serially or spatially correlated observations, generalized
linear models, and quantile regression.
