[R] Ubuntu sources file for R packages

[Naresh Gurbuxani]

I followed these instructions to install R on my new Ubuntu desktop.

https://cran.r-project.org/bin/linux/ubuntu/


To install additional packages, I am following these instructions:

https://cran.r-project.org/bin/linux/ubuntu/fullREADME.html


For Ubuntu 26.04 (Resolute Racoon), /etc/apt/sources.list is 
deprecated.  It seems I need to create a file in 
/etc/apt/sources.list.d/.  I started a file "r-package.sources" and need 
entries for the last two fields.  My file:

## R package repository
Types: deb
URIs: https://cloud.r-project.org/bin/linux/ubuntu
Suites: resolute-cran40
Components:
Signed-By:

It will also benefit other users if you can update the instructions in 
fullREADME.html


Thanks,

Naresh
