Hi maicel,
This may be completely off the mark, but the brkdnNest function in the
plotrix package can produce a nested list of counts which can be
transformed into percents (100*count/total).
require(plotrix)
data$dummy<-1
brkdnNest(dummy~Provincial+Municipios+unit,data,FUN="sum")
The counts in your example are mostly NA as most cells are empty.
