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
