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

[akshay kulkarni]

Dear members,
                            I have a script which I source it interactively. I have the following questions:


  1.  If there is an error in an expression, an error message is printed, but the execution continues till the end of the script. I am sourcing with echo. 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()?
  2.  I am trying to abort the execution with ESC key, but again the same thing happens: it aborts the current expression but continues on. How to abort an R script with source()? I am using RStudio in windows.

Please help,

THanking you,
Yours sincerely,
AKSHAY M KULKARNI
