Coordinates of a circle

Description

Define the coordinates for drawing a circle

Usage

circle(
  size.x = 10,
  size.y = size.x,
  pos.x = 0,
  pos.y = 0,
  lty = 1,
  lwd = 3,
  shd = NA,
  vis = 1
)

Arguments

size.x

numeric, define the semi-major axis of the ellipse within which the figure is inscribed. Default is 10

size.y

numeric, define the semi-minor axis of the ellipse within which the figure is inscribed. Default is size.x

pos.x

numeric, position on the x axis. Default is 0

pos.y

numeric, position the y axis, Default is 0

lty
