## Decorate Heatmap Dendrograms

### Description

Decorate Heatmap Dendrograms

### Usage

    decorate_dend(heatmap, code, slice = 1, which = c("column", "row"),
        envir = new.env(parent = parent.frame()))

### Arguments

`heatmap` | Name of the heatmap.
`code` | Code that adds graphics in the selected heatmap dendrogram.
`slice` | Index of the row slice or column slice in the heatmap.
`which` | Is the dendrogram on rows or on columns?
`envir` | Where to look for variables inside `code`.

### Details

If you know the number of leaves in the dendrogram, it is simple to calculate the position of every leave in the dendrogram. E.g., for the column dendrogram, the i^th leave is located at:

        # assume nc is the number of columns in the column slice
        unit((i-0.5)/nc, "npc")

### Value

This function returns no value.
