Excuse me for a so dummy question, but I really can't manage to do this 
very simple thing : I have a data frame, and I would like to calculate 
two vectors which contain the sums respectively of the rows and of the 
columns of the matrix.

There is surely a very simple way to do that, but I didn't find it...

Many thanks in advance.
