[R] R in Batch mode

[Bos, Roger]

Duncan's suggestion is probably the way to go, but I will just point out
that R does have a facility to perform a task when an error occurs.  I
have my code set up to send me an email when my batch code fails.
(email() is a function I wrote that executes sql command to send email
via dbmail.)

.Err <- function() {email("roger.bos at rothschild.com","!Notify: Job
FAILED on " %+% Sys.info()[4],"","TEXT","HIGH")}
options (error = .Err)

Thanks,

Roger

This is really an Ubuntu question, isn't it?

I'd suggest writing a script which calls your R batch file.  The last
thing the batch file should do is write some sort of status value.  The
last thing the script should do is check and act on the status.

Of course, if whatever kills your batch file kills the script too,
you're out of luck.
