Decorate Heatmap Dimension Names
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 |
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")
The function returns no value.

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)
