If you want your code to be compatible with
S+, then 'seq_len' isn't going to work.

R-people,

Duncan Murdoch's response in

https://stat.ethz.ch/pipermail/r-help/2010-February/227869.html

reminded me of something I had been meaning to ask.

A while ago I started using

for(i in seq_len(v)) {....}

in preference to

for(i in 1:n) {....}

Duncan's post shows that if n can be zero, there is
an advantage to using seq_len.
Is there ever a *dis*advantage?
