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.

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

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