[R] installing R on Ubuntu, can ignore warning messages?

[Robert Wilkins]

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!
2: List the R-related packages and add-ons that are available?
Probably a big number of them?

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:
https://help.ubuntu.com/community/RootSudo

thanks again.
