The main subtlety is that on Windows you need to install most of the 
tools yourself.  Read the instructions in the R Installation and 
Administration manual, and follow them exactly.  A common error is not 
to put the R tools first in the PATH; then Windows finds the wrong 
commands, and things go wrong.

I don't know what debugging tools are available, other than editing the 
scripts to print things out as they go along.  The scripts are normally 
installed in the RHOME/bin directory.
