The two sets of packages I use a lot for their utility functions and for
making my day-to-day analysis and reporting easier are Hmisc and Design
by Frank Harrell and {gdata,gmodels,gplots} by Greg Warnes. Frank's
packages have good documentation and cover a pretty good range of
regression methods as well as a refined set of report-writing tools (see
http://biostat.mc.vanderbilt.edu/twiki/bin/view/Main/RS for more). These
aren't "obscure" or "small" tools, but very useful and "cool" tools I
use regularly.
Greg and Frank can thank me later for the free plug :-D :-D

Hi,
I'm relatively new to R, so I don't know the full list of base (or
popular add-on packages) functions and tools available. For example,
I tripped across mention of rle() in a message about some other
problem. rle() turned out to be a handy shortcut to splitting some of
my data by magnitude (vaguely like a sequence-based histogram).
So I thought I'd ask: what small, or obscure, tools and functions in R
do you find handy or 'cool' to use in your work?
Thanks
Carl
