Hi,

in last nights alpha version, `var' is broken:

R> var(rnorm(100))
Error in var(rnorm(100)) : 3 arguments passed to "cov" which requires 4.

which I suspect is due to recent changes to `cov'. The same is true for

R> cov(rnorm(100), rnorm(100))
Error in cov(rnorm(100), rnorm(100)) : 3 arguments passed to "cov" which
requires 4.


Best,

Torsten

Yes these two are related, but the e-mail subject is wrong:
It's *your* fault because you must have unpacked the new version
on top of an older one.
The official alpha version (Snapshots from here, or rsync) do
not have your problem:
Before a few days ago, there were files  
    src/library/base/R/var.R
    src/library/base/R/cov.R
the newer R-alpha do not have them -- and if you use the old
files where you shouldn't --> you get the problem.

yes, thats the problem, however it is a problem with rsync. I
update the tree via

	rsync -rC rsync.r-project.org::r-devel R

an this does not remove those files:

hothorn@www:~/software/R/src/library/base/R$ ls -la cov.R
-rw-r--r--    1 hothorn  users         375 Sep 12 04:00 cov.R
hothorn@www:~/software/R/src/library/base/R$ ls -la var.R
-rw-r--r--    1 hothorn  users         361 Sep 12 04:00 var.R

A possible fix is using

	rsync -rC --delete rsync.r-project.org::r-devel R

(maybe one should add a hint in section 2.4 of the FAQ).

Thank you for pointing this out!

Best,

Torsten

no, but with the options you use it with...   ;-)

Of course, I've always used something like the above -- that's
why I said above rsync would also give the correct files...

Definitely.
