can you please stop repeating this nonsense? I don't think anybody
ever claimed that vectors can be considered list. It's rather the
other way round: lists can also be seen as vectors to R (possibly they
are implemented as such, but I don't much about the internals of R).

Honestly, I can't think of a situation where I would want to do than
in R. In a Perl script, quite likely; but this is a kind of data
manipulation that R wasn't really designed for IMHO.
Not that I'd mind having sort() operate properly on lists; it just
isn't something I miss in the language.
