[R] Count number of different patterns (Polytomous variable)

["Biedermann, Jürgen"]

Hi there,

Does anyone know a method to calculate the number of different patterns 
in a given data frame. The variables are of polytomous type and not 
binary (for the latter i found a package called "countpattern" which 
unfortunately only functions for binary variables).

V1   V2   V3
0   3   1
1   2   0
1   2   0

So, in this case, i would like to get "2" as output.

Thanks in advance
Jürgen
