Make polygon_list ellipses

Description

Make polygon_list ellipses

Usage

polygon_ellipses(
  xcenter,
  ycenter,
  setnames = NULL,
  xradius = 1,
  yradius = 2,
  rotation_degrees = c(0),
  n = 60,
  ...
)

Arguments

xcenter, ycenter	numeric vector that defines the x and y coordinate position of the center of each ellipse.
setnames	vector that contains names for each circle, stored as names() for each polygon. When setnames is NULL then index numbers are used.
xradius, yradius	numeric vector that defines the radius of each ellipse along the x-axis and y-axis, respectively. Each vector is recycled to length(xcenter).
n	integer value indicating the number of subdivisions to use in the circle.
...	additional arguments are ignored.
rotation_degree	numeric vector representing degrees to rotate each ellipse after it is created, where values are conformed to between 0 and 360, rotating clockwise.

Details

This function creates one or more ellipses as polygon_list list objects.

Value

object list with a number of circles encoded as polygons.

Examples

polygon_list <- polygon_ellipses(c(3, 2), c(2, 3),
   xradius=c(1, 4),
   yradius=c(5, 2))
plot_polygon_list(polygon_list, col=c("#FF000077", "#FFDD0077"));
points(x=c(3, 2), y=c(2, 3), pch=c("1", "2"), add=TRUE);
