plot a legend for a pedigree

Description

circular legend for a pedigree as a key to the affection statuses

Usage

pedigree.legend(
  ped,
  labels = dimnames(ped$affected)[[2]],
  edges = 200,
  radius = NULL,
  location = "bottomright",
  new = TRUE,
  density = c(-1, 35, 65, 20),
  angle = c(90, 65, 40, 0),
  ...
)

Arguments

ped	Pedigree data frame with ped (pedigree id), id (id of individual), father (id of father), mother (id of mother), sex, affected (affection status), and avail (DNA availability).
labels	names for the affected indicators
edges	Number of edges for each polygon. Higher numbers give better resolution for the circle
radius	radius (inches) of the circle
location	similar to how the location of a base-R legend is given, used only if new=TRUE. A character string indicating which of the four corners to plot the legend, given by "bottomright", "bottomleft", "topleft", or "topright".
new	Logical. If TRUE, plot the legend on the current plot. Otherwise, plot on a separate plot.
density	Density of lines shaded in sections of the circle. These match the density settings for the plot.pedigree function.
angle	The angle at which lines are shaded in sections of the circle. These match the angles for the plot.pedigree function.
...	optional parameters for the plot function that apply to text
