[R] Ubuntu sources file for R packages

[Robert Dorazio]

Naresh,

The instructions given at https://cran.r-project.org/bin/linux/ubuntu/  for
installing R on Ubuntu work well.

However, for installing R packages I recommend the following approach.

1. Download the shell script for your version of Ubuntu (e.g.,
add_cranapt_resolute.sh for Ubuntu 26.04) from
the r2u website:  https://github.com/eddelbuettel/r2u

2. Run the shell script from the terminal as follows:
sudo su
bash add_cranapt_resolute.sh
exit

Then you have two options for installing R packages from the fast,
well-connected mirror  r2u.stat.illinois.edu

As an example, you can install the R package "sp" using either of the
following options:

1. From the terminal:  sudo apt install r-cran-sp

2. From R:  install.packages("sp")

A big advantage of using r2u is that all dependencies of each package are
downloaded properly.
