Concordance to the consensus partition

concordance(membership_each, class)

Arguments

membership_each: A matrix which contains partitions in every single runs where columns correspond to runs. The object can be get from get_membership(..., each = TRUE).
class: Consensus subgroup labels.

Details

Note subgroup labels in membership_each should already be adjusted to the consensus labels, i.e. by relabel_class.

The concordance score is the mean proportion of samples having the same subgroup labels as the consensus labels among individual partition runs.

Value

A numeric value.
