No nothing :((((
I tried :

# make the graphics device high enough to hold Albania
x11(height=10,width=5)
# display the map upon which you want the pies
hdf <- get_map(location = c(20.166065, 41.270679), zoom = 8,
maptype = 'roadmap')
ggmap(hdf, extent = 'device')
# I don't know if you have to do anything else here
# 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)
but pffff nothing
What to do
Look at the documentation for ggmap (I don't have the package on my
system, so I can't do it for you). Try par("usr") to see the coordinates
of the plot.
