Updates metadata(x)$comparison$colors using a user-supplied named color vector. Comparison colors are used in fold-change and comparison-level plots. The color map must include all currently active comparisons.

Usage

set_vista_comparison_colors(object, color_map)

Arguments

object: A VISTA object.
color_map: Named character vector of colors, with names equal to comparison names (for example "A_VS_B").

Value

A modified VISTA object with updated comparison colors.

Examples

v <- example_vista()
comps <- names(comparisons(v))
if (length(comps)) {
  cmap <- stats::setNames(rep('#1b9e77', length(comps)), comps)
  set_vista_comparison_colors(v, cmap)
