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
