How to install R and Rstudio under Ubuntu Linux 20.04

This tutorial also installs the free, open-source program R for statistical computing, as well as a graphical user interface (GUI) for R known as Rstudio, under Ubuntu Linux version 20.04

This tutorial assumes you are using Ubuntu Linux version 20.04 as your operating system. If you do not have a computer running Ubuntu, fear not. You can install Ubuntu as a virtual machine within your current operating system. It is all free.
The instructions for Windows computers are here:
The instructions for Mac computers are here (from 0:00 to 5:37):

Code I used in this tutorial:

sudo apt update
sudo apt -y install r-base gdebi-core
cd Downloads
^^^^^change this filename to the one you downloaded!

But you can actually skip this tutorial if you just use my pre-configured Ubuntu Linux virtual machine! Read more below.

FYI:
I have made a Linux virtual machine that is pre-configured with population genetics and ecological niche modeling programs. I have made videos explaining how to hook up this virtual machine within your Mac or Windows computer, so that you can start using the pre-configured software without having to install any of them (and even without having to install Ubuntu Linux!).

wow for some reason I tried doing this myself a bunch of times and after an hour I figured lets try youtube. This video was clear concise and worked perfectly! Thank you for your attention to detail!

Thanks, I spent two days trying to figure out how to install this in a Google Chromebook, and your video made it so easy to go.

I first tried to directly install R studio with sudo commend, which is successful installed however cannot open it, thanks to this video that I realized that I need to install the R package for my system first then could install R studio.

Thank you! first time using linux, found an old 2011 macbook pro 17in replaced OS w/Ubuntu and thought why not use it for coding.

Hi is this on Wayland? Does Rstudio support Wayland yet?

[DB-polh]

Thank you, I've successfully installed rstudio with your tutorial. You said that you have population genetics software installed on your virtual machine. Do you know any open source alternatives to AlleleA1 software?

[leolomardo]

Its taking forever to download it? it took that much time for you too?

Thanks for the video. Just one additional question, should I install the R and RStudio directly in my system, or installing in a conda env may be a better option? Could some one help me?
