[R-sig-Epi] (mapplots): adding labels in draw.pie from a data.frame

[Gianpaolo Romeo]

Hi,

(first of all: sorry for my english...)

I need to plot some pie charts on a map (one over each region) but I don't
know how to use two colomns from a data.frame as text: can you help me to
use the arguments "labels" in the right way? I need to plot the percentage
of Females near the F-slice and the Male near the M-slice.
I've plotted the pies but the problems is the label.
Another question is: i don't understard the values of "radius" and
"scale"...


Best regards,

Gianpaolo

#this is the data.frame "perc"


      F    M
1  13 % 87 %
2  13 % 87 %
3  13 % 87 %
4  15 % 85 %
5  20 % 80 %
6  15 % 85 %
7  16 % 84 %
8  16 % 84 %
9  20 % 80 %
10 16 % 84 %
11 15 % 85 %
12 15 % 85 %


#and this is the code for plotting the pies

draw.pie(xyz$x, xyz$y, xyz$z, radius = 15000, col = alpha(c("deeppink",
"DodgerBlue"), 0.3), scale = T)
