I have little doubt, and I do not think that the way I solve the problem
is the best way to do it.
The following is a small dataset

OT?: International number parsing
Can anyone shed some light on "rules" that might make the task of
parsing the country code and city codes from a dialed number in the
CDRs?
I know that there is almost never a case where a concatenated country
and city code could overlap with another country code, but what about
city codes and local numbers? Is it possible for a concatenated city
code and local number to match another

barplot that displays sums of values of 2 y colums grouped by different variables
It is not generally advisable to get too fancy with stat functions in
ggplot... things can easily get more complicated than ggplot is ready to
handle when it comes to calculations. It is better to create data that
corresponds directly to the graphical representations you are mapping
them to.

of course I get just one data point, the mean Height for
