Subject: Re: [R] How to *completely* stop a script after stop()?

I too am encountering this problem.  When I have a large 
script, if I select
all in the editor and then ctrl-r to run, if it encounters a 
stop() function
it simply prints an error message and continues to execute 
the remainder of
the script, as opposed to terminating execution at that line. 
 The quit()
function exits R altogether, which I don't want.  Yes, I 
could manually
select only the portion of script which I want to run, but for lengthy
scripts which I run repeatedly (generally changing only the 
name of the file
I want analyzed), this can be quite tedious.  It appears that the only
solution is to put most of the code in a separate file and 
call it using
source(); this has the downside of reducing the clarity of 
the code -- it's
a sort-of structural spaghetti code approach.
