R help - May 2007 - how to abort script with message

it is desired to abort an R script with a message, returning to the R
prompt,
pending 'if' results, as follows:
------------------------
first part of script
.
.
if (condition) {
 action
} else
{
'error'
abort
}
.
.
remainder of script
---------------------------

note: 'stop' aborts the current script expression but keeps running the
script.[too little]
        'quit' aborts the r session. [too much]
thx,
ted

Hi,

I think the behavior that you outline is due to the fact that you
cut'n'paste the script to the R prompt, is that correct? If so, use
source() instead to run your script, then stop() will do what you
want.
