Plot a radial polygon — radialPolygon • sonicscrewdriver

Used to plot sectors, annuli and horizons on a dielPlot() or yearlyPlot(). The polygon has an inner and outer horizon - which can be set to a fixed radius or a vector.

Usage

radialPolygon(
  angle1,
  angle2,
  radius1,
  radius2,
  col = "grey",
  border = NA,
  rot = -pi,
  angleinc = 0.01,
  reverse = TRUE,
  ...
)

Arguments

angle1: Angles for the inner line
angle2: Angles for the outer line
radius1: Radii for the inner line
radius2: Radii for the outer line
col: Colour of the polygon
border: Border colour (see polygon() for details)
rot: Rotation of the plot, defaults to pi to match dielPlot() and yearlyPlot()
angleinc: The angular increment in radians for calculating circular lines
reverse: If FALSE plots in an anti-clockwise direction
...: Other parameters passed to polygon()
