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?
If I understood the previous para:
as.data.frame( xtabs( ~. , as.data.frame( x ) ) )
HTH,
Chuck
Thanks for any assistance!
Greg
