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.
