Okay, let's try again.

# get yer data
sampledf<-read.table(text="x y City Village
  19.9437314 40.7086377 120 425
  20.2214171 41.4924336 1 1
  20.0955891 39.9481364 4 4
  20.9506636 40.6447347 10 15",header=TRUE)
# make the graphics device high enough to hold Albania
x11(height=10,width=5)
# display the map upon which you want the pies
map(xlim=c(19,21.1),ylim=c(39.5,42.6))
# display the pies
library(plotrix)
for(pp in 1:4) floating.pie(sampledf[pp,"x"],sampledf[pp,"y"],
  unlist(sampledf[pp,c("City","Village")]),radius=0.1)
