Manual ggplot2 scales from a persistent color map — scale_color_sc

These scales use the exact named assignments stored in map; assignments are never recomputed from the plotted subset.

Usage

scale_color_sc_map(map, ..., drop = TRUE)

scale_colour_sc_map(map, ..., drop = TRUE)

scale_fill_sc_map(map, ..., drop = TRUE)

Arguments

map: An sc_color_map.
...: Passed to ggplot2::scale_color_manual() or ggplot2::scale_fill_manual().
drop: Drop unused factor levels from the scale.

Value

A ggplot2 scale.

Details

Use the color or colour variant for points, lines, text, and geometry outlines mapped with color. Use the fill variant for geometry interiors mapped with fill, such as violins, bars, tiles, and polygons. The scale_colour_*() spelling is an exact alias of scale_color_*(). For a one-off categorical plot that does not require locked assignments, use the _sc_d() family; for numeric gradients, use _sc_c().

Examples

map <- sc_color_map(c("B", "T", "NK"))
ggplot2::ggplot(
  data.frame(x = 1:2, y = 1:2, cell = c("T", "NK")),
  ggplot2::aes(x, y, color = cell)
) + ggplot2::geom_point() + scale_color_sc_map(map)
