First off, you've named your variable for an existing function, which
can cause all kinds of problems.

Second, this should work just fine, as it does for me:

> maxvar <- 4
> for(i in 0:maxvar) cat(i, "\n")
0
1
2
3
4

What leads you to think that it's not working?

There's a better way to ask your question, at least: give us
reproducible code, and explain what you are not seeing that you expect
to see, or vice versa. "seems to miss out on the first value" - what
happens? If I can't reproduce it, I can't help you solve it.
