Draw a pie chart

Description

Draw a pie graph evenly divided into polygons each colored according to the specified colors (cols) The center of the pie chart is at coordinates x, y and the radius is defined by rad

Usage

draw_pie(
  x = 0.5,
  y = 0.5,
  radius = 1,
  cols = c("red", "green"),
  border_col = "black",
  node_border_lwd = 1,
  labels = NULL,
  edges = 200,
  label_cex = 1,
  xlim = NULL,
  ylim = NULL,
  add = TRUE
)

Arguments

x	the x coordinate for the center of the pie chart
y	the y coordinate for the center of the pie chart
radius	The radius of the pie chart
cols	A vector of colors in any format specifying the colors of the sections of the pie chart. The number of colors determines the number of sections in the pie.
border_col	The color of the border of the pie chart. Use NA to omit the border.
node_border_lwd	The thickness of the border line
labels	A vector of character values giving labels for the sections of the pie.
edges	The default value is 200, which generates a circle. Reducing this number will result in other shapes that may or may not produce meaningful graphs depending on the number of pie sections.
label_cex	A numeric value giving the size of the label text.
xlim	A vector of length two giving the xlim of the plot if add is FALSE
ylim	A vector of length two giving the ylim of the plot if add is FALSE
add	A logical value indicating whether the pie should be added to an existing plot (TRUE) or drawn on a new plot (FALSE).
