projectionNumber

Given two partitions (p, q) represented as vectors of cluster ids,
compute the projection number which is the sum of maximum
cluster overlaps for all clusters of \(P\) to any cluster of \(Q\).

Provides several measures ((dis)similarity, distance/metric,
correlation, entropy) for comparing two partitions of the same set of
objects. The different measures can be assigned to three different
classes: Pair comparison (containing the famous Jaccard and Rand
indices), set based, and information theory based.
Many of the implemented measures can be found in
Albatineh AN, Niewiadomska-Bugaj M and Mihalko D (2006)
<doi:10.1007/s00357-006-0017-z> and
Meila M (2007) <doi:10.1016/j.jmva.2006.11.013>.
Partitions are represented by vectors of class labels which allow a
straightforward integration with existing clustering algorithms
(e.g. kmeans()). The package is mostly based on the S4 object system.
