FW: Select a random subset of rows out of matrix
Dear all,
I have a large dataset (N=100,000 with 89 variables per subject). This dataset is stored in a 100.000 x 89 matrix where each row describes one individual and each column one variable.
What is the easiest way of selecting a subset of let's say 1.000 individuals out of that whole matrix?
Thanks,
Michael
