Try this,
library(ggplot2) d <- data.frame(theta = runif(10, 0, 360), r = runif(10, 0, 3)) ggplot(d, aes(x=theta, y=r, size=r)) + coord_polar(start=0)+ geom_point() + scale_x_continuous(breaks=seq(0, 360, by=30), expand=c(0,0), lim=c(0, 360))+ scale_area() HTH, baptiste On 28 June 2011 10:35, Patrick Jemison <jemi...@gmail.com> wrote: > I'd like to create a polar plot similar to those created by the polarFreq > function in the openair package.
