Show colors spread around a pie chart

Show colors spread around a pie chart

Usage

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.
