While the installation file mentions
/usr/local as the default location, it's possible that the R installation process chose a different directory on your Debian 12 system. Here's how to find the directory and completely delete it:
1. Find the R installation directory:
There are a few ways to find the directory where R is installed:
This will show you the location of the R binary and other R-related files.
During the installation process, the system logs should have recorded the installation directory. You can search the logs using a command like:
grep R /var/log/*
- Look for the R executable:
Try searching for the R executable using a command like:
find / -name "R"
This will search your entire system for files named "R".
2. Delete the R installation directory:
Once you have found the R installation directory, you can delete it using the
sudo rm -rf command. For example, if the directory is
/usr/local/lib/R , you would use the following command:
sudo rm -rf /usr/local/lib/R
Important: This command will permanently delete the R installation directory and all its contents. Make sure you have backed up any important data before proceeding.
3. Remove R-related packages:
In addition to the main installation directory, R might have installed additional packages in other locations. To ensure a complete removal, you can also remove these packages using the
sudo apt purge r-base-core libcurl4-gnutls-dev libxml2-dev libssl-dev
4. Remove the R repository and key:
If you added an R repository during the installation process, you can remove it using the following command:
sudo apt-key del E084DAB9
This will ensure that R packages are not automatically installed again in the future.
