Hi,
Look at

?findInterval

this looks it best/exactly suits your needs.

Subject: [R] Vector Manipulation

Greetings,

I wonder if someone could point me towards a more elegent solution than
what I"ve kluged together.  I have a vector "samp1" of 296 integers.
They are sorted in ascending order and the numbers range from 177 to
228,953.  I'd like to specify N non-overlapping intervals covering the
range from 0 to 229,354 and then for each range, count the number of
integers from samp1 that fall into that range.  What I'll end up with is
an N element vector with each element representing the number of
integers from samp1 found in the Nth range.

Can someone point me to a function / procedure that allows me to specify
the non-overalpping intervals? and also one that I can use to do the
counting?

Best,
Bill Vedder
