Completely Uninstall R Linux

completely uninstall r linux

The R binary (well, front-end script) is part of the r-base-core package which contains the core R system.

The package r-base is a so-called virtual package which exists to just pulls other packages in. Removing it does not remove any parts of the R system --- for which you need to remove r-base-core.

Unistall R completely from Linux Mint 19 and do a fresh install

I gave up on Linux Mint and installed Ubuntu 20.04. R 4.0.2 works out of the box and the problem is solved.

Complete remove and reinstall R, including all packages

In R, you can use the .libPaths() instruction (or R -e '.libPaths()' in terminal) to know where your packages are installed. Delete those folders and reinstall.

How to uninstall R and RStudio with all packages, settings and everything else?

I have further issues with the previous answer. For that reason, I have extended the answer with further steps (which I experienced currently) as below:

1. Run .libPaths() and save the listed directories shown on the RStudio console. In my case, it looks like:

.libPaths()

"C:/Users/%USERNAME%/Documents/R/win-library/3.6" 
"C:/Program Files/R/R-3.6.3/library"

2. Uninstall R for Windows, RStudio and RTools from Windows "Programs and Features" menu. You might navigate there through: Add or remove programs > App & features > On search box

3. Delete everything in folders that was shown after running .libPaths() instruction in R to know where R packages are installed.

Therefore, I have manually deleted following files and folders (they remain there after full uninstallation of R, RStudio and RTools) as well:

C:\Users\%USERNAME%\Documents\R\
C:\Users\%USERNAME%\Documents\.Rhistory
C:\Users\%USERNAME%\AppData\Local\Temp > only specific ones mentioned below.

Specific ones can be various files and folders which can be deleted under this directory related with R and RStudio sessions. In my case, Rtmpcx1qAZ, Rtmpk7UXWj, Rscript3d2438240e1, ... are only example files or folder names to give you rough idea.

4. Delete everything inside those listed folders or completely delete those listed folders as well:

C:\Users\%USERNAME%\AppData\Local\R
C:\Users\%USERNAME%\AppData\Local\rstudio
C:\Users\%USERNAME%\AppData\Local\RStudio-Desktop
C:\Users\%USERNAME%\AppData\Local\r-miniconda
C:\Users\%USERNAME%\AppData\Local\r-reticulate
C:\Users\%USERNAME%\AppData\Local\??? (!!!might be some others in your case!!!)
C:\Users\%USERNAME%\AppData\Roaming\R
C:\Users\%USERNAME%\AppData\Roaming\RStudio

Then you can move on the re-installation side for R as below (after suggested reboot of Windows). In order (please):
Download R for Windows, (download RTools if you need) and RStudio Desktop.

• Install R (R for Windows)
• Install RTools (if you need)
• Install RStudio (RStudio Desktop)

R redhat uninstall

So it turns out that the problem is that I needed to uninstall several other R packages to actually rid the system of all the environmental variables that were screwing up the reinstall. The following commands totally uninstalled R:

yum uninstall R
yum uninstall R-core
yum uninstall R-devel
yum uninstall R-core-devel

And that did it for me. From there I was able to successfully reinstall R.
