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.
