I'm observing odd behavior of the rep(...) procedure when using variables as
parameters in a loop. Here's a simple loop on a vector 'branches' that is
c(5,6,5,5,5). The statement in question is
print(c(ni,rep(i,times=ni)))
that works properly first time through the loop but the second
Cannot reproduce, what is branches? If you can narrow it down to a
commented, minimal, self-contained, reproducible example, you're far
more likely to get help from the list.

My blinded guess though, is something to do with FAQ 7.31.
Sorry, not reproducible. This works for me (as expected):
branches-c(5,6)
iInd = 1
for(i in 1:length(branches)) {
print((1:branches[i])+iInd-1) # iInd is a position shift of the index
ni = branches[i]
print(i)
print(ni)
print(c(ni,rep(i,times=ni)))
# ... some interesting other

That's what I did. 'branches' was shown at the top.
branches = c(5,6,5,5,5)
I tested this. When I copy and paste into R 10.0 I get the result in the
post. Perhaps I should reinstall R. I guess I don't see how much more
narrow I can get than this.
i iInd = 1
for(i in
I could send the entire bit of code but I was hoping that someone would
recognize the issue from past experience. I may be an artifact of other
parts of the code. I observed the problem in a larger context and cut
out all that you see below. The comments were next to the results to
clarify.
What does
print(as.integer(branches))
give? That is what rep() uses.
