There are many other options. Please check my e-mail with dir and ls

Would you please elaborate on this?

This one (as many others) I may consider Vista issues as well.

Again, I'm not pro or con cygwin. I actually do not want R on it.

I suffer it too :-) and wholeheartedly sympathize you.


Thanks for the good news. Although it might be a little bit late - it
was not there when I badly needed it now that I have Solaris 10 OS x64 R
I barely would use it. Sorry. Please no bad feelings.

OK, I take my words back - it's not "far far" it's only "far away" (or
even only "away" if this makes you happier :-). Meaning not _only R
itself but Windows as well_, i.e., the platform plus R. I admit my
initial statement was not that clear, sorry. As you can see here no
blames on R (core :-).

I agree but would use stronger expression here close to "never". And
this is one reason to try minGW (AFAIK they are close to have 64-bit of

I personally use whatever is most appropriate and hate it to be any
flavor of Windows but ... Again, how is Rgui more "native Windows
version" then plain native Windows CLI version? Are you using/confusing
"native"s two possible meanings here? One being minGW meaning of
"native" and the other as in "native Windows user" :-)))
