I'm surprised too -- good catch.

Add to package utils in R-devel, after correction. I was surprised you had fallen into the 1:0 trap:
x <- character(0)[1] NA
head(x)
is not I think what anyone wants.

Note that `R base' could mean the base package or the R distribution, and I don't know which is meant. Could one of you please clarify?
The base package in R-devel is much reduced, but these could be a candidates for the `utils' (or perhaps `tools') packages.

1. Add "head" and "tail" to R base. Patrick Burns has these: http://www.burns-stat.com/pages/public.html#genutil
Very handy functions for checking data manipulation.
How about we just add these to a package available on CRAN? How about we just make a package of the Burns Statistics functions? There are already .Rd files...
I do have plans of a package of Burns Statistics functions, but haven't
got around to it yet. However, I do agree with Kevin that "head" and
"tail" are good candidates for base (though I'm not sure it would be
number 1 on my wishlist). "head" and especially "tail" have value in
programming as well as interactive use, which I think is a stronger
argument for inclusion in base than just being handy interactively.
