I believe that previously could not be understood. To facilitate'll give you
an example. Assuming my table is presented below with the amount received
from each candidate for president in a particular country state.
AL AR CA NY
Doug 250 250 250 NA
Jennifer 20 340 300 100
Michele 250 500 250 60
Obama 15 45 520 600
I would like to list the states where Obama has higher amount received (ie
in CA and NY) and also the number of states, in this case 2. How to do this?
