Decorate Heatmap Dimension Names

1 2	decorate_dimnames(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 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`.

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:

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

The function returns no value.
