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

[akshay kulkarni]

Dear Duncan,
                         What if I use source() with echo? I am using that in RStudio.

THanking you,
Yours sincerely

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 file and the execution aborts. Is there a way to mimic this with source()?

I don't see this behaviour.  If I put this in a script:

  print(1)
  stop("here")
  print(2)

then execution stops at the "stop" line if I use source(), or R CMD
BATCH <file>, or in RStudio, Run or Source gives the same behaviour.  I
think older versions of RStudio would have run all three lines using
Run, but all the other methods have stopped at the stop() line.
