slice {dendroextras} | R Documentation

## Cut a tree-like object into groups numbered in tree order

### Description

In comparison with cutree, the groups are numbered from left to right as per the tree when plotted in its standard horizontal form. Note also that the return value will have the leaves sorted in dendrogram order.

### Usage

    slice(x, k = NULL, h = NULL, ...)

### Arguments

`x` | tree like object
`k` | an integer scalar with the desired number of groups
`h` | numeric scalar with height where the tree should be cut
`...` | Additional parameters passed to methods

### Value

a named vector with group memberships

### Examples

    hc <- hclust(dist(USArrests), "ave")
    # return groups, leaves ordered by dendrogram
    slice(hc,k=5)
    # return groups, leaves ordered as originally passed to hclust
    slice(hc,k=5)[order(hc$order)]
