cluster2keys {psych} | R Documentation |
The output of the kmeans clustering function produces a vector of cluster membership. The score.items
and cluster.cor
functions require a matrix of keys. cluster2keys does this.
cluster2keys(c)
c |
A vector of cluster assignments or an object of class ``kmeans" that contains a vector of clusters. |
Note that because kmeans will not reverse score items, the clusters defined by kmeans will not necessarily match those of ICLUST with the same number of clusters extracted.
keys |
A matrix of keys suitable for score.items or cluster.cor |
