Returns the Rand index, the corrected Rand index or the asymmetrical Rand index. The asymmetrical Rand index (corrected or not) measures the inclusion of a partition 'P' into and partition 'Q' with the number of clusters in 'P' greater than the number of clusters in 'Q'.
rand(P, Q, symmetric = TRUE, adj = TRUE)a factor, e.g., the first partition.
a factor, e.g., the second partition.
a boolean. If 'FALSE' the asymmetrical Rand index is calculated.
a boolean. If 'TRUE' the corrected index is calculated.
