dear R-community,
Is it possible to have one pie chart of a large radius and then a pie
chart with smaller radius placed on top of the larger so the centers of
the two pie charts coincide?
I managed to place a filled circle with smaller radius in the piechart,
see below.
Thanks in advance, Sybille
pie(rep(1,12), col=rainbow(24), radius=0.9, labels=
c("J","F","M","A","M","J","J","A","S","O","N","D"),clockwise=T)
points (0,0,col="black",cex=20,pch=1
