Dear all, I am working in a code whose goal is the selection of matrix rows according to their column values.
The problem is that the matrix I am working with has 60 columns per 6.000.000 rows, so I am looking for the most efficient way to perform the selection. Any hint about that? Thanks in advance Juan _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
