color_repel: Reorder ggplot colors to maximize color differences in space

Description

Reorder ggplot colors to maximize color differences in space

Usage

color_repel(
  g,
  coord = NULL,
  groups = NULL,
  nsamp = 50000,
  sim = NULL,
  severity = 0.5,
  verbose = FALSE,
  downsample = 5000,
  polychrome_recolor = FALSE,
  seed = 34,
  col = "colour",
  autoswitch = TRUE,
  layer = 1,
  out_orig = FALSE,
  out_worst = FALSE,
  ggbuild = NULL
)

Value

vector of reordered colors

Arguments

g

ggplot plot object

coord

coordinates, default is inferred

groups

groups corresponding to color/fill, default is inferred

nsamp

how many random sampling color combinations to test, default 50000

sim

passing a colorbind simulation function if needed

severity

severity of the color vision defect, between 0 and 1

verbose

whether to print messages

downsample

downsample when too many datapoints are present, or use chull

polychrome_recolor

whether to replace the original colors with polychrome creation

seed

sampling randomization seed

col

colour or fill in ggplot

autoswitch

try to switch between colour and fill automatically

layer

layer to detect color, defaults to first

out_orig

output the original colors as named vector

out_worst

output the worst combination instead of best

ggbuild

already built ggplot_built object if available

Examples

a <- ggplot2::ggplot(ggplot2::mpg, ggplot2::aes(displ, hwy)) +
  ggplot2::geom_point(ggplot2::aes(color = as.factor(cyl)))
new_colors <- color_repel(a)
b <- a + ggplot2::scale_color_manual(values = new_colors)
