First, if you look carefully, then you see that argument 'files'
should specify *filepaths*, i.e. directories and not specific files.
Thus, if you for instance place your files in directory foo/ and
then call
tar(foo.tar, files=foo/);
you would do the right thing.

assume I have an existing file 'pathname' and I want to rename it to
'pathnameN' (which does not exist). I use:
res - file.rename(pathname, pathnameN);

Hi,
I've just created:
newEnvEval - function(..., hash=FALSE, parent=parent.frame(), size=29L) {
envir - new.env(hash=hash, parent=parent, size=size);
evalq(..., envir=envir);
envir;
} # newEnvEval()
so that I can create an environment and assign objects to it in one go, e.g.
env -
It should be possible to run unique()/duplicated() column by column
and incrementally update the set of unique/duplicated rows. This
would avoid any coercing. The benefit should be even greater for
data.frame():s.

See onSessionExit() in the R.utils package, e.g.
onSessionExit(function(...) {
cat(Bye bye world!\n);
})
quit();
Please pay attention to the Details section of help(onSessionExit);
there are ways that R can exit that will not be detected/handled.

Some already know, but I think it deserves a bit of a attention here as well:
It looks like we're about to get new features in R that will be very powerful!
That should be a good enough teaser for now...

Hi,
in Section 'Writing package vignettes' of 'Writing R Extensions' it says:

after the Sweave runs, so PDF manuals can be created from arbitrary

is executed

thanks. I like that idea of the output parameter better, especially if we

I am also in favor for keeping the ability of installing directory

I've got some questions regarding finalizers registered using

a new finalizer to an object that already got one. Since there is no

Hi,
while backtracking why sort(NULL) gives a warning, and acknowledging
that NULL is not the same as an empty vector and sort(NULL) is bad
coding, I discovered the following inconsistency of sort.int():
x - NULL

I don't make announcements of the changes, you just need to check the web

I think normalizePath() has been moved to 'base' very++ recently. /H

This might have been discussed before, but below is a
not-so-unlikely use case where the user follows normal procedures,
updates R to a major release version, and then R crashes:
1. Use runs R stable (e.g. v2.13.0).
2. User installs a package with a namespace, e.g. install.packages(fortunes).
