Dear fellow R-users,

Say we have a matrix x, defined as follows

set.seed(50)
x <- matrix(rbinom(100*5,1, p=0.75),nrow=100, ncol=5)

Now the interpretation of x is that each for of x is actually a sequence of length 5, and i would like to transform x in such a way that I can describe the frequencies of sequences observed among the 100. How can I do this efficiently?

Thanks for any assistance!
Greg
