Hi, I have a 5x3 matrix and wish to remove the 2 rows that contain the lowest value in the 3rd column. For example, if the matrix was as shown below, the second and last rows would be deleted, since they contain the smallest values in the final column (0.096177... and 0.095584...)
Any help would be greatly appreciated!

See the second output of mink() to get the indices that you can then use to delete with.
