Dear Duncan,

RStudio.
THanking you,
Yours sincerely

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.
