140 packages in R Commander!!
Dear List
I just downloaded and installed R 2.12.0 and then installed R Commander .
First it got RCmdr and Car, and then suggested for other packages for
utilizing the full functionality- I clicked yes!
I got 140 packages installed!!! Cran Mirror was UCLA...
Here is the list.
Is this intentional- I can see some packages like snow and multicore which
are desirable but quite optional.(see list

Rserve alternative?
The Rserve documentation at
http://rosuda.org/Rserve/doc.shtml#start
states that even when making multiple connections to the Rserve,
Windows won't separate workspaces physically and share environments,
which will obviously cause problems and should therefore not be used.
Are there any alternatives for the windows platform?

Debian ?Ubuntu version of latest R using synaptic in Ubuntu 10.10
Dear List
I use synaptic to download R on my Ubuntu 10.10. It seems latest version of
R on Ubuntu is 2.11.1
Even when I use debian.cran.r-project.org to update my packages the problem

packages) This is also true for a lot of other packages as well
My specific problem is while I can use sudo apt-get to update packages

Problems in Recommending R
Dear List,
One persistent feedback I am getting to people who are newly introduced to R
( especially in this cost cutting recession) is -
1) The website looks a bit old.
While the current website does have a lot of hard work behind it, should n't
