um_partition | R Documentation |
Check whether partitions of the figuration matrix are unimodular. For partitions A=A1 A2, the function um_partition computes the determinants of A1 for all possible (unique) combinations of rows. Function um_partition_sample coputes determinants of A1 for a sample of those partitions.
