cutree {mva} | R Documentation |
Cuts a tree, e.g., as resulting from hclust
, into several
groups either by specifying the desired number of groups or the cut
height.
cutree(tree, k=NULL, h=NULL)
tree |
a tree as produced by hclust |
k |
An integer scalar or vector with the desired number of groups |
h |
A numeric scalar or vector with heights where the tree should be cut. |
At least one of k
or h
must be specified, k
overrides h
if both are given.
cutree
returns a vector with group memberships if k
or
h
are scalar, otherwise a matrix with group meberships is returned
where each column corresponds to the elements of k
or h
,
respectively (which are also used as column names).
require(mva) data(USArrests) hc <- hclust(dist(USArrests)) cutree(hc, k=2:5) cutree(hc, h=250)
