So the center will be (0,90) and the outer circle's second coordiante will be zero (the horizon). This might sound strange – even for Australien people (-; Thomas This requires an extra argument to the function. I've included it and will probably upload a new version of plotrix within a week. I didn't quite understand your request for an example in which the center is not contained in the polygon. If you can explain this a bit, I would be happy to include a better example.

[R] plotrix: reverse axis in polar.plot
Hi, how can I reverse the radius axis of plotrix's polar.plot function? Perhaps this sounds strange, but I use the radians for angles as well: In the center is zenith and the corresponding angle is 90°, not 0. See an example plot at http://www.mysundial.ca/tsp/images/sun_chart_50_solar_polar.jpg dirs-c(S,E,N,W) polar.plot(NA,NA,label.pos=seq(0,270,length=4),labels=dirs,main=Sun Chart,rp.type=p,radial.lim=c(0,90)) lines(c(4,12,15,22,45,55),c(10,83,118,90,72,61),col=red) And why is the radial limit in the above example 0..100 and not 0..90 as requested by the radial.lim argument?
