[R] aborting the execution of a script...

[akshay kulkarni]

Dear Duncan,
                         But it is entirely different in my case...! As you said, the problem may be with my version of RStudio. The main point is that it doesn't pose any serious problems...

Thanks any way for your reply...

Thanking you,
Yours sincerely,
AKSHAY M KULKARNI

This is what I get:

 > source("~/temp/test.R", echo = TRUE)

 > print(1)
[1] 1

 > stop("here")
Error in eval(ei, envir) : here

I get similar output in every variation I tried.  It never prints the 2.

Is there any way to abort the execution when the first error occurs? This happens with R CMD BATCH.  If there is an error midway, an error message is printed in the output
