Need help installing Linux software on daughter's computer

Dear community,

I gave a Lenovo T480S computer installed with Zorin 16.3 core. I was surprised that in one of her university courses is requesting that students install R-CRAM software: The Comprehensive R Archive Network

She is a psychology student and she will be doing some programming. I do not understand, but this is beside the point.

She is alone to have a Linux based computer and luckily, this software is available for Linux. I have followed the guide on how to install on her computer which is here: Ubuntu Packages For R - Brief Instructions

However, I have no clue on how to start the program. They say that we need to type r in the terminal to start. Does not work.

I checked in the installed applicaitons, I do not see it installed.

Can someome provide some guidance please? I'm lost.

Thank you kindly,


I believe that's capital R:

OMG... it worked!!!

How silly of me. Thank you so much ZenZen.

I'm getting the hang of this.

No problem! :slight_smile: A famous quote goes like this:

So yeah, even capital letters can be tricky.

While you are at it you might want to setup an alias so that r and R run the same program. Open a terminal and run:

echo 'alias r=R' >> ~/.bashrc

Make sure you use two angle brackets, that's really important, otherwise you'll overwrite the entire file instead of appending to it.


@zenzen After doing further reading, we need to install R-Studio. I did accomplish it as well.

Do you know what this programing language is? My daughter says that this is for statistical analysis.

Just curious. I'm learning alot.

I've never used it myself, but my understanding is that it's used for that purpose: statistics, creating charts, etc. I found this FAQ to answer some of those basic questions and satisfy one's curiosity:

R: What is R?

Thanks. I have some understanding of what it is. Now installed in my computer, i will do it in hers.

I read the instructions that are geared towards Windows and Mac. Thank god that this is native on Linux as well.

I appreciate your help.
