summary function to use, default is mean, options are mean, median, sd, var, mad, max, min, and sum
Iheatmap-class object, which can be printed to generate
an interactive graphic
If adding the column summary to a vertically oriented heatmap, the summary will be based on the topmost heatmap if side is "top" and based on the bottom heatmap if side is "bottom" unless a "heatmap_name" is specified. The heatmap_name should match the "pname" argument given to a previously added heatmap.
The column summary is based on specific rows if a "groups" argument
is given. The groups argument can either be a vector of group assignments for
each row, the "pname" for an existing set of groups incorporated into the
groups is set to TRUE, then the function will use an existing set of row
groups added to the plot.
