Decorate Heatmap Dendrograms

Decorate Heatmap Dendrograms

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.

Examples

set.seed(123)
Heatmap(matrix(rnorm(100), 10), name = "mat", km = 2)
decorate_dend("mat", {
    grid.rect(gp = gpar(fill = "#FF000080"))
}, which = "row", slice = 2)
