[FEATURE] Allow custom legend titles for row_side_colors in ggheatmap()

[juliagcurras]

Hi there!

I'm trying to figure out whether it's possible to change the legend title for the grouping column when using the row_side_colors argument in the heatmaply::ggheatmap() function.

Here’s a minimal example using the iris dataset:

heatmaply::ggheatmap(
  x = iris[, -ncol(iris)],
  row_side_colors = iris[,"Species", drop=F]
) 

Output:

I've tried various combinations of RowSideColors, row_side_colors, and row_side_palette, but I haven’t found a way to modify the legend title.

Thank you very much in advance for any help!

Best,
Julia

You would probably be as well off returning the plots and modifying them with standard ggplot2 tools
