[R] Package functions to be included in R

[Murray Cooper]

A recent thread on summary statistics, got me thinking. (Note this may not
happen often.) A function that would do summaries as describe below (similar
to SAS PROC UNIVARIATE) might be a nice addition to the main R system. Is
there a process by which functions, from packages can eventually be
incorporated into R. The reason I ask, is having them in R would guarantee
they get adequate testing. This would be helpful, for GLP and GCP
validation.
