NA's?

Wed, Mar 30, 2005 5:22 PM
I have a large matrix of data .

The size of the matrix ranges from 100 x 100 to 1000 x 1000

Now i have to do computations on that. And should not consider the diagonal 
elements.

I tried setting diag(M) = NA  and M = na.omit(M).

But this omits all the rows. I only want to omit that diagonal elements only 
but consider the whole row.

diag(M) = 0 seems like a good option but this will affect my result.

How to proceed with this. How to just ignore some specific values. what if i 
want to consider only the upper / lower triangular matrix
