 i have this error:

Error in rep.int(c(1, numeric(n)), n - 1L) : negative length vectors

This is the second time in two days that you post the same question. The 
reason that you didn't receive an answer is not that you didn't post
often
enough...it's that it's hard to say anything with the information you 
provide. See the posting guide (link given below) on how to ask a better 
question.
