Decorate Heatmap Dendrograms

1 2	decorate_dend(heatmap, code, slice = 1, which = c("column", "row"), envir = new.env(parent = parent.frame()))

`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`.

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:

1 2	# assume nc is the number of columns in the column slice unit((i-0.5)/nc, "npc")

This function returns no value.
