R help - Apr 2005 - Error list and debugging R code

Hi,

I am trying to debug my code and looking for any tool to help me out with
it. My main problem is with the error messages I can not figure out where
they come from (what function produced them) and what do they mean. Is there
such a think as list of error messages produced by R and standard R
packages,  and what do they mean? Or any tool to extract information which
function produced the run-time error (a call stack would be great)? I looked
into debug and trace tools but you seem to have to know where the problem is
to use them.

See any good book about R programming, the manuals, R News, and the 
following help pages:
?traceback
?debug
?recover
?browser
and other relevant pages these pages are pointing to.
