R devel - Sep 2003 - `var' broken in 1.8.0 alpha (2003-09-15)

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.
