In happynotes/RoundAndRound: Plot Objects Moving in Orbits

Description

Plot in polar coordinate system

Usage

plotpcs(theta, a = 1, ab = 1, orig = c(0, 0), fun = graphics::plot,
  ...)

Arguments

theta	Angle in polar coordinate system
a	Radius of start and end points of the arrow.
ab	Semi-major over semi-minor. ab=1 for a Ring.
orig	Origin
fun	Plot function. default = plot
...	More options in plot function

Examples

n=50
par(mfrow=c(2,1))
plotpcs(theta = 1:n * 15, a=1:n/10, ab=1, type='l', asp=1)
plotpcs(theta = 1:n * 10, a=1:n/10, ab=1, type='l', asp=1)
xy = PCS2CCS(theta = 1:n * 10, a=1:n/10, ab=1)
xy[,1]=xy[,1]+1
points(xy, pch=19, col=terrain.colors(nrow(xy)))
