sjc.cluster: Compute hierarchical or kmeans cluster analysis

Description

Compute hierarchical or kmeans cluster analysis and returns the group association for each observation as vector.

Usage

sjc.cluster(data, groupcount, method = "h", distance = "euclidean",
  agglomeration = "ward", iter.max = 20, algorithm = "Hartigan-Wong")

Arguments

Value

The group classification for each observation as vector. This group classification can be used for sjc.grpdisc-function to check the goodness of classification. The returned vector includes missing values, so it can be appended to the original data frame data.
