Another wishlist for R
Add to package utils in R-devel, after correction. I was surprised you had fallen into the 1:0 trap:
x <- character(0) head(x)
[1] NA 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. On Wed, 21 Jan 2004, Patrick Burns wrote:

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...
This sounds suspiciously like an editorial "we". 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.
