plot_pie function

Visualize biogeographic patterns using pie charts

plot_pie(
  omega,
  pol,
  radius = 0.55,
  col = hcl.colors(5),
  pie_control = list(),
  legend = FALSE,
  legend_pie = FALSE,
  ...
)

Arguments

• omega: a matrix of phyloregion of probabilities of each species
• pol: a vector polygon of grid cells with a column labeled grids .
• radius: Radius of the pie legend to be displayed
• col: List of colors for the pies.
• pie_control: The list of control parameters to be passed into the add.pie function.
• legend: Logical, whether to plot a legend or not.
• legend_pie: Legend for the pie plots.
• ...: Further arguments passed to or from other methods.

Returns

Returns no value, just map color pies in geographic space!

Examples

library(terra)
data(africa)
p <- vect(system.file("ex/sa.json", package = "phyloregion"))
K <- ncol(africa$omega)

CLRS <- hcl.colors(K)
plot_pie(africa$omega, pol = p, col=CLRS)
