Hi List,

I've got a count matrix like this:      


                  [-11.9,-11] (-11,-10.2] (-10.2,-9.3] (-9.3,-8.44]
[-11.9,-10.6]            0           0            0            0
(-10.6,-9.3]             0           0            0            0
(-9.3,-8.01]             0           0            0            0
(-8.01,-6.73]            0           0            0            0

I want to manipulate the matrix by taking the average of each range, eg. [-11.9,-11] as (-11.9-11)/2. I've tried R introduction and site search, but not able to find information relevant.

Thanks!

Jen
