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.
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.
