validate.partialorder.incidence {parsec}

validate.partialorder.incidence

Description

The function checks whether the boolean square matrix m represents a partial order. If yes, the function returns the same input matrix as a S3 class object incidence. Otherwise, the unfulfilled partial order properties of matrix m are returned.

Usage

validate.partialorder.incidence(m)

Arguments
