Re: [R] favorite useful tools?

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
