try this:
DF <- data.frame(V1 = c(0,1,1), V2 = c(3,2,2), V2 = c(1,0,0))
DF
nrow(unique(DF))
I hope it helps.
Best,

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
