Returns the current Posit Package Manager (PPM) repository URL
Value
String scalar, the repository URL of the configured PPM
instance. If no PPM instance is configured, then the URL of the Posit
Public Package Manager instance. It includes the repository name, e.g.
https://packagemanager.posit.co/all.
Details
This URL has the form {base}/{repo}, e.g.
https://packagemanager.posit.co/all.
To configure a hosted PPM instance, set the PKGCACHE_PPM_URL
environment variable to the base URL (e.g.
https://packagemanager.posit.co).
To use repo_add() with PPM snapshots, you may also set the
PKGCACHE_PPM_REPO environment variable to the name of the default
repository.
On Linux, instead of setting these environment variables, you can also
add a PPM repository to the repos option, see base::options().
If the environment variables are not set, then ppm_repo_url() will
try to extract the PPM base URL and repository name from this option.
If the PKGCACHE_PPM_URL environment variable is not set, and the
repos option does not contain a PPM URL (on Linux), then pkgcache
uses the public PPM instance at https://packagemanager.posit.co, with
the cran repository.
