It does, thank you. I was able to understand enough of it to do the
install successfully . Still trying to understand the later paragraphs
such as install.package() and the r-cran-foo build dependencies. (the
site you pointed me to is the same site i did a printout of yesterday
to try to do an install, the readme file prints to 3 pages).
Is there an easy way to:
1: List the R-related packages and add-ons that are already installed?
no point in trying to install what you already got!
installed.packages()
2: List the R-related packages and add-ons that are available?
Probably a big number of them?
Larger innumber than you would want to print. Why not go to CRAN with
your browser?
Also, for people who try Ubuntu out for the first time could be thrown
for a loop by the weird way it handles the root account:

thanks again.

Hi,
Instructions for authenticating the cran repositories are here:
http://cran.r-project.org/bin/linux/ubuntu/
r-base comes with whatever the base R libraries are (stats, graphics
etc.). I don't know if MASS in particular is in base because I don't
use it directly.
As far as I know it's safe to ignore the warnings, but they annoy me
so I always following the instructions linked above.
The list of packages regularly updated in the cran repo are also
listed on the webpage linked above.
A couple of further tips:
1) I usually install packages with sudo aptitude install r-cran-xxx
and then make sure they are up-to date by running update.packages()
in
R.
2) You can also install packages using the regular install.packages()
in an R session.
Hope that helps,
-Ista

Installing R on Ubuntu 8.10,
( using sudo apt-get install r-base , and using one of the cran
sites
(cran.cnr.berkeley.edu))
the installation process says something about not having some gpg
public key and
"are you sure you want to download non-authenticated stuff [y/
n]" (to
which I answered yes).
I'm assuming this warning can be ignored?
Also: even though the Ubuntu install and online update did a GCC
install the other day, the R installation did an update of some GCC
files, which I thought was odd. Probably I can ignore that too.
Once you've installed R, does that automatically include some data
examples ( such as that MASS library ? )?
Or does that require further downloads?
Also, thanks for the previous tips
