Hi dear R list members,

These are warnings and I think that you can safely ignore them.
It looks like the code should replace the line

Yes, I think so too - thanks for reporting this.

Hi
You did not provided any suitable data.
x-sort(sample(letters[1:5], 50, rep=T))
unlist(lapply(split(x,x), function(x) (1:length(x))-1))
gives you a vector of indices from 0 to n for sorted vector x.
