[R] Sweave template

[Frank E Harrell Jr]

Dear Group,

I have made significant improvements to our Sweave template, have made 
the template self-contained (i.e., you can run it yourself and it will 
find the datasets it needs), and have included the output pdf file. 
This is at http://biostat.mc.vanderbilt.edu/SweaveTemplate .  You will 
see in the pdf file the enhancements in how R code is pretty-printed, 
and I have added an example where some R function output is suppressed 
from the listing that Sweave typesets.  The new template also suggests 
how to auto-document the computing environment at the end of the report, 
and how to properly reference R and add-on packages.  Figures are 
centered (but not as nicely as Marc Schwartz' approach) and better 
defaults are used for axis label and tick mark label positioning.

Thanks to Romain Francois for providing the trick of suppressing parts 
of R output (replacing it with ...) and Peter Ruckdeschel for his 
excellent SweaveListingUtils package.  Suggestions for further 
improvements are welcomed.

Frank
