Decorate Heatmap Dendrograms
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 |
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")This function returns no value.
