(just a comment)
and since this appears to be O(m^2 x n), where m,n are the number of
rows and columns (correction requested if I got this wrong), it would
appear that some basically C level functionality -- perhaps the one
Jean suggested? -- would be required for even moderately large
Jorge,
I have not used it myself, but you might find the dist() function in the

Dear all,
Given vectors x and y, I would like to compute the proportion of
entries that are equal, that is, mean(x == y).
Now, suppose I have the following matrix:
n - 1e2
m - 1e4
X - matrix(sample(0:2, m*n, replace = TRUE), ncol = m)
I am interested in calculating the above proportion for
