say 'm' is your matrix, then try
rowMeans(m * col(m))
I hope it helps.

I have a small matrix where the columns represents a ranking and the values
are the number of times each ranking was obtained eg
1 2 3
x 1 2 0
y 0 1 2
z 2 0 1
I'd like to be able to return an average of the ranking obtained
average
x 1.67
y 2.67
z 1.67
Whats the nicest way to do this? I'm new to the language and looking for an
elegant solution :)
Thanks
Ben
