Rscript not returning zero - R-devel

Sat, Oct 17, 2009 7:06 PM #

Hi

I'm trying to run a R script in a computer grid using the Rscript
interpreter, but the Rscript is not returning zero (even when the
scripts processes succesfully) on its exit which causes the scheduler
to detect an error and not records the output.

Is there any way to get the Rscript returning zero ?

R version 2.9.2 (2009-08-24)
x86_64-unknown-linux-gnu

attached base packages:
[1] stats     graphics  grDevices utils     datasets  base
sh-3.2$ echo $?
0

so please give a reproducible example of a successful script not 
returning zero.

Moreover, Rscript and r (i.e. littler) both support custom return codes:

edd at ron:~$ Rscript -e 'q(42,save="no")'
edd at ron:~$ echo $?
42
edd at ron:~$ r -e 'q(42,save="no")'
edd at ron:~$ echo $?
42
edd at ron:~$
