Dear R-devel,
Apologies for bothering y'all with this seemingly perennial question. A
user reported problem with my most recent version of randomForest (4.4-1),
and I was able to reproduce it with his data with R-2.0.0 patched
(2004-10-24) on WinXP Pro. The problem is that it crashes R on Window

I will be taking over as maintainer of the its package from Giles Heywood.
The code was originally written while he was working at Commerzbank. I have
added the header below to the top of the R source file to indicate the
changes in the copyrights for the code. The package was originally released
A little code study, formula study and experimentation reveals that the
situation is mostly fixable:
1. Get rid of the explicit alpha limit. (A form of it is implicit in
(2) and (3) below.)
2. Use the series formula when
(x < alph + 10 && x < 0.99 * (alph + 1000))
This guarantees

Yes, but only with the intention of using the installation to compile
packages for windows.

This has nothing to do with write.table. The column names in x are
"x" and "x.1".
This is documented in the NEWS file:
o data.frame(check.names = TRUE) (the default) enforces unique
names, as S does.
