[R] evaluate return values of commands executed with system()

[Rainer M Krug]

Hi

I would like to check the return value of commands executed with system()

I am using Linux (Ubuntu Hardy) and I am executing GRASS commands and
would like to call stop() when they return an error (i.e. return code
= 1).

Thanks

Rainer
