Build one shared color palette across every value in an annotation data frame

heatmaply's col_side_colors/row_side_colors mechanism encodes the values of all annotation variables onto a single combined color scale, so a single palette covering every unique value across every column is needed, rather than one palette per column.

Usage

combinedAnnotationColors(sample_annotation)

Arguments

sample_annotation

A data frame with sample metadata

Value

output A named vector of colors, one per unique value across all columns of sample_annotation
