...cles of radius 40 respectively 60 (The first argument of "line" should be the angle, the second the length.)? Or: which function plots in existing polar plots? (Remark the the polygone is not complete, eg going around) My final goal will be such a plot: http://www.mysundial.ca/tsp/images/sun_chart_50_solar_polar.jpg which is the polar-coordinate version of my wikimedia plot http://commons.wikimedia.org/wiki/File:Sonnenstand.png (made in R, see source) Thanks for hints and help, Thomas PS: I asked a close question last year: http://www.mail-archive.com/r-help at r-project.org/msg64998.html

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...
