Best way to install R on Ubuntu 20.04?

问题

Does anyone have a good approach to installing R on Ubuntu 20.04? I can't seem to find a solution for this specific to 20.04 focal through apt.

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04 LTS
Release:    20.04
Codename:   focal

Edit: after going through the link here and adding the entry to sources.list, I ran into issues with dependencies:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 r-base : Depends: r-base-core (>= 4.0.2-1.2004.0) but it is not going to be installed
          Depends: r-recommended (= 4.0.2-1.2004.0) but it is not going to be installed
          Recommends: r-base-html but it is not going to be installed

Per @DirkEddelbuettel's comment, I ran sudo apt install r-base-core r-recommended r-base-html to see next level dependencies:

There was a more underlying issue when I worked on trying to install r-base. I ended up finding out that I had problems with unmet dependencies after adding a PPA. I used this link here to fix the underlying problem of unmet dependencies, which in turn allowed me to apt install and not have any issues installing.

回答1:

Here is what I do in the Rocker container r-ubuntu for the 20.04 image:

Install software-properties-common to be able to say add-apt-repository
Add the rrutter4.0 PPA for R itself (same as CRAN)
add-apt-repository --enable-source --yes "ppa:marutter/rrutter4.0"
Add the c4d4u.teams repo for over 4k CRAN packages:
add-apt-repository --enable-source --yes "ppa:c2d4u.team/c2d4u4.0+"
Run apt install r-base (and a few more).

In a narrow sense you only need 2 (as you likely do not 1 on a full Ubuntu system) and 4 but you may as well do 3.

You can of course also just to docker pull rocker/r-ubuntu:20.04 and get that container pre-made, but I use both: a container for tests, and these settings on my 20.04 machine(s).
