R help - Dec 2009 - [Fwd: snowfall on Win7]

Dear Ola,

I cannot say anything about Windows 7, as we do not have any Win7
machines here in our institute and I even do not know someone who have
Win7 on a private machine. I will try to find a machine with this OS and
test it.

Anybody having experiences with Win7 yet?

Greetings Jo

R 2.10.1 installed today on win7 works fine for this new user.  Although the
demos fail with a complaint about unable to "setwd"    I suspect
it's a
privaleges problem.   Win7 is awkward about install privaleges. I suspect my
working directory is in "Admin" land; and I'm trying to execute
from
/user/tom      If I could figure out a function to have R list my
environmental variables; I could probably figure it out.....
    I have two processor on my Toshiba...
