Dear Mailing List Members,

the problem I've been grappling with für quite some time now is the following:

I have a 100 rows x 200 columns matrix.

data.set <- matrix(rnorm(20000, 100, 200))

Now I would like to get a vector of length 100 which collects the values from the following procedure:

Take the sum of the minima of the two values from each row of columns 1 and 101, and divide it by the sum of column 101.
Do the same for column 2 and 102, 3 and 103 and so on.

Thanks a lot for your help.

Alrik
