I think there are two issues:
1. You need the rworldxtra package to get the countriesHigh dataset so adding in
library(rworldxtra) is necessary.
2. I think you need to "focus" the figure to a smaller area and add in a
statement
like mapRegion="Somalia" in the mapPies function.

Subject: [R-sig-Geo] Fwd: Pie charts on a map. v2
Dear sirs/madams,
May someone please help me with this issue: I have been trying to plot pie
charts on a map, without much success (see code enclosed herein). This is quite
distressing to me, as I had plot the same kind of map before without problems.
It would be appreciated if anyone would point out the flaw. I enclose a
reproducible set of data and codes for you to work with. I have tested the
code, you just have to paste the three of the files in the same folder.
Thank you very much in advance.

P.S.: My e-mails asking for questions are sometimes quite short and can seem
rude, I am sorry for that. The truth is that I hearfully appreciate any help of
yours.
