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
- ...
