agreement | R Documentation |
Calculates the agreement between two partitions, typically the known actual cluster labels and the predicted cluster labels.
agreement(predicted, actual, method = "cRand", na_as_cluster = TRUE)
predicted |
a vector with predicted cluster labels. |
actual |
the known cluster labels (ground truth). |
method |
the used method (see |
na_as_cluster |
logical; should |
This convenience function is an interface to clue::cl_agreement()
. See methods
in that man page
for a list of available methods. A measure typically used for clustering is the corrected Rand index
(also called adjusted Rand index). Numbers close to 1 indicate a very good agreement.

# Perfect agreement (1 and 2 are just switched) actual <- c(2, 2, 1, 3, 2, NA) predicted <- c(1, 1, 2, 3, 1, NA) agreement(actual, predicted) # No agreement predicted <- sample(predicted) agreement(actual, predicted)
