[GRASS-user] return value of modules?

[Rainer M Krug]

Hi

do the modules of R (e.g. r.stats, ...) have return values which I can
evaluate to find out if the execution was successful? E.g. returning
-1 when an error occurred?

I would like to use these "return values on error" to evaluate the
success of the command when called from R.

Thanks,

Rainer
