Hi,

Given a test matrix, test <- matrix(c(1,2,3,NA,2,3,NA,NA,2), 3,3)

A) How to compute the counts of each column (excluding the NA) i.e., 3, 2, 1

B) How to compute the counts of each column (excluding the NA) that are
greater than the column means ? i.e., 1, 1, 0

I could write a for loop, but hope to use better alternative.
