SR,
My answer to the question you posed is "Someone must know, but I do not
know".
However, I suspect the answer to the question you should have asked is:
See
?cut
and
?findInterval
HTH,
Chuck

There are a total of 60 lines and I get a "contextstack overflow" error
at line 50. From reading the archives, it looks as though this is a
hard limit but can be changed rather easily. Unfortunately, I haven't
found any specifics on how to change this limit. Does anyone know how I
can edit this upper limit?
Thanks,
SR
