Dear R People:

I'm running from R to a grid computer and getting some unusual results
with the system command:

> e7 <- system("globus-job-run xxxxx /bin/sh -c 'cd $OSG_APP/engage;chmod 777 oops'",intern=TRUE)
chmod: changing permissions of `oops': Operation not permitted
> e7
character(0)
>


I xx'ed out the site name.  Anyhow, I would expect that the e7 would
contain the warning.  Is there any way to have e7 contain the warning
please?

Thanks,
Erin
