ppm_snapshots {pkgcache}

List all available Posit Package Manager (PPM) snapshots

Description

List all available Posit Package Manager (PPM) snapshots

Usage

ppm_snapshots()

Details

The repository URL of a snapshot has the following form on Windows:

{base}/{repo}/{id}

where {base} is the base URL for PPM (see ppm_repo_url()) and {id} is either the date or id of the snapshot, or latest for the latest snapshot. E.g. these are equivalent:

https://packagemanager.posit.co/cran/5
https://packagemanager.posit.co/cran/2017-10-10

On a Linux distribution that has PPM support, the repository URL that contains the binary packages looks like this:

{base}/{repo}/__linux__/{binary_url}/{id}

where {id} is as before, and {binary_url} is a code name for a release of a supported Linux distribution. See the binary_url column of the result of ppm_platforms() for these code names.

Value

Data frame with two columns:

• date: the time the snapshot was taken, a POSIXct vector,

• id: integer id of the snapshot, this can be used in the repository URL.
