that might and only use
point-in-polygon on the potentially outside points. However, I'd try the
point-in-polygon route first and see if it is fast enough first.

Sounds like you need a "point-in-polygon" routine to determine if the jittered
point is still within the polygon.
R has several such routines. Here are two:
pnt.in.poly in the SDMTools package
point.in.polygon in the sp package
Mathematica has several options, too.

I now see the issue: you have lat and long reversed in pie.chart.txt. That
puts you in Somolia and Kenya (which is why I suggested mapRegion=Somalia
earlier).

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.

It sounds like the function .negloglik.boxcox is being fed some parameters it
doesn't like (and possibly it doesn't like the starting values). Possibly
attempting to divide by zero. So I would first check .negloglik.boxcox with
the starting values to see if something other than infinity comes
rad.mult.fact has length 6 and rad.add.fact has length 5. Does that affect the
calculations?

When you also simultaneously post the question elsewhere
(http://stackoverflow.com/questions/25531430/rgeos-error-when-using-gunaryunion),
please note that to both lists.
And that post has more useful information included than the post to this list:
Just for dissolving I use the rgeos
