See ?hist
For example
hist(rnorm(100),plot=F,breaks=-3:3)$counts

Subject: [R] frequencies
Hi
I have a set of fish lengths (cm) which I'd like to
have divided into bins as specified by myself. I want
to classify my bins as:
0<=x<0.5
0.5<=x<1
1<=x<1.5
1.5<=x<2
and so on...
I'd like the frequencies to be given as a vector
because I need to use these values for further
analysis.
Please can someone help me with this. I can't find a
command in R that allows one to do this.
Many thanks.
Silvia Kirkman

You want the function cut(), followed by table().
