Dear R user group,
I wish to plot small pie-charts to specific coordinates in a e.g.
scatter-plot:
E.g.:> plot(rnorm(100),rnorm(100))
> points(1,1,col="red",cex=4)
-> I wish to put pie(c(2,3)) at the position of the red circle...
How can I do this efficiently?
Thanking you and wishing you a wonderful Sunday!
Georg.
