Installing R

We recommend installing multiple versions of R because an environment with multiple versions of R helps provide a stable, reproducible environment for your R developers.

Install R using the directions at https://docs.rstudio.com/resources/install-r/.

Recommended installation directories

Posit Workbench automatically scans for versions of R at the following locations:

/usr/lib/R
/usr/lib64/R
/usr/local/lib/R
/usr/local/lib64/R
/opt/local/lib/R
/opt/local/lib64/R

In addition, Posit Workbench scans all subdirectories of the following directories within /opt:

/opt/R
/opt/local/R

For example, any of the following installed versions of R will be automatically detected by Posit Workbench:

/opt/R/4.2.2
/opt/R/4.3.0
/opt/local/R/4.2.2
/opt/local/R/4.3.0

If you have versions of R located at other places in the file system, Posit Workbench can still utilize them. However, you’ll need to explicitly specify their location in a configuration file (this is covered in more detail in the Using Multiple Versions section).
