Setting Default Repositories in Workbench
For R
In R, default repositories are set using files at the server, R version, user, or project level.
In most Workbench installations, server admins set a binary Package Manager repository as the default.
| File | Level | Use |
|---|---|---|
rsession.conf |
Whole Server | Configuring single repo server-wide |
repos.conf |
Whole Server | Configuring multiple repos-server wide |
Rprofile.site or Renviron.site |
Version of R | Configuring different repos per R version |
rsession.conf
Admins configuring a single server-wide default repository for Workbench, you can use the r-cran-repos argument to the rsession.conf file. This argument can only take a single repository.
For example, on a Ubuntu Bionic installation of Workbench, an admin might configure
/etc/rstudio/rsession.conf
r-cran-repos=https://packagemanager.posit.co/all/__linux__/bionic/latestrepos.conf
Admins configuring multiple server-wide default repositories for Workbench can use the repos.conf file.
For example, on a Ubuntu Bionic installation of Workbench, an admin might configure
/etc/rstudio/repos.conf
CRAN=https://packagemanager.posit.co/all/__linux__/bionic/latest
Internal=https://my-package-manager/internal/__linux__/bionic/latestRprofile.site
Admins configuring repositories that are specific to R versions can use either Rprofile.site files.
These files are set for each version of R and should be located in $R_HOME/etc/. You can find R_HOME by running the command R.home(component = "home") in a session of that version of R.
For example, if you find that $R_HOME is /opt/R/3.6.2/lib/R, the Rprofile.site for R 3.6.2 would go in /opt/R/3.6.2/lib/R/etc/Rprofile.site.
Rprofile.site files are sourced as regular R code, so setting the repository might look like
/opt/R/3.6.2/lib/R/etc/Rprofile.site
options(repos = c(CRAN = "https://packagemanager.posit.co/all/__linux__/bionic/latest"))"For Python
In Python, repositories can be set in a pip.conf file. These can be set globally for all versions of Python at /etc/pip.conf.
To set a repository for a particular Python version, a virtualenv should be used, and the repository can be set in $VIRTUAL_ENV/pip.conf.
The pip.conf might look like: /etc/pip.conf
