R help - Dec 2009 - "R CMD BATCH" continue after an error in the script

Hi,
I have a problem with R CMD BATCH, because I created a .bat file to run a
script:

C:\R\R-2.9.2\bin\R CMD BATCH C:\Scrip_test.R

It work perfectly but after 3 lines of script there is a line with a nls()
function that cannot be fitted and this end in an error message.
I'm not bother by the error message, I just want that the script continue.

If I use the R windows GUI the script show the error message but it continue
till the very end.
I want that the script continue to run also in BATCH mode, How can I do that?

Many thanks in advance,
Fabio

Fabio,

If you're not using the nls() function's result, then why don't you
comment
it out from the script? That way, there will be no error and the script will
work fine.

Please post your script if you need further help.

The try function will provide a mechaism for gracefully "stepping  
around" coding potholes.
