## Decorate Heatmap Dimension Names

### Description

Decorate Heatmap Dimension Names

### Usage

    decorate_dimnames(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 viewport.
`slice` | Index of the row slice or column slice in the heatmap.
`which` | on rows or on columns?
`envir` | where to look for variables inside `code`.

### Details

If you know the dimensions of the matrix, it is simple to calculate the position of every row name or column name in the heatmap. E.g., for the column column, the i^th name is located at:

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

### Value

The function returns no value.

### Examples

    set.seed(123)
    mat = matrix(rnorm(100), 10)
    rownames(mat) = letters[1:10]
    colnames(mat) = LETTERS[1:10]
    Heatmap(mat, name = "mat", km = 2)

    decorate_dimnames("mat", {
        grid.rect(gp = gpar(fill = "#FF000080"))
    }, which = "row", slice = 2)
