Show colors spread around a pie chart

color_pie(
  colors,
  border = colors,
  lwd = 2,
  radius = 1.1,
  label_radius = radius * 0.65,
  add = FALSE,
  init.angle = NULL,
  clockwise = TRUE,
  ...
)

Arguments

colors: vector of R colors.
border: vector of R colors used to draw a border around each pie wedge. By default it uses input colors.
lwd: numeric value used to define the line width of the pie wedge borders.
radius: numeric value representing the radius of the overall pie chart, where radius=1 represents the default radius used by graphics::pie(). The default is radius=1.5 in order to use more of the output plot size.
label_radius: numeric value indicating the radius used for labels, intended to allow labels to appear inside each pie wedge.
add: logical indicating whether to draw the pie chart onto the existing plot device, without creating a new plot.
...: additional arguments are passed to graphics::pie().

Details

This function simply displays colors in a pie chart format.

If the input is a list, each list is used to produce layers of a pie chart, in order to help compare colors from each vector in the list.

Examples

color_pie(rainbowJam(15, nameStyle="none"),
   sub="rainbowJam(15)")


n <- 12;
color_pie(list(
   rainbowJam(n),
   rainbow(n)),
   main="rainbowJam(12) [outer]\n       rainbow(12) [inner]")


n <- 15
color_pie(list(
   rainbowJam(n),
   rainbow_hcl(n, c=85)),
   main="rainbowJam(15) [outer]\nrainbow_hcl(15) [inner]")


rainbow_list <- lapply(4*c(5,4,2,1), function(n){
   rainbowJam(n, preset="ryb", step='v23', nameStyle="n");
});
color_pie(rainbow_list,
   main="preset='ryb'\nstep='v23",
   sub="rainbowJam()\nn=4, 8, 16, 20")


rainbow_list2 <- lapply(4*c(5,4,2,1), function(n){
   rainbowJam(n, nameStyle="n");
});
color_pie(rainbow_list2,
   main="default settings",
   sub="rainbowJam()\nn=4, 8, 16, 20")


rainbow_list3 <- lapply(4*c(5,4,2,1), function(n){
   rainbowJam(n, preset="dichromat", step="v23", nameStyle="n");
});
color_pie(rainbow_list3,
   main="preset='dichromat'\nstep='v23'",
   sub="rainbowJam()\nn=4, 8, 16, 20")
