When content is deployed, Packrat records details about how a package Publishers configure repositories locally on theirĬomputers. Posit Connect support alternate repositories in addition to CRAN, which canĬontain private packages. Most public packages will come from a public CRAN mirror, but Packrat lets Repositories hosted on GitHub, GitLab, orīitbucket that are visible to Connect's configured Git accounts.

Deployments are faster when they can take advantage of Other ShinyĪpplications built with the same version of the shiny package will use thatĬached installation. That version of shiny is placed into the packrat package cacheĪnd associated with that Shiny application deployment. Shiny package, for example, is installed when the first Shiny application isĭeployed. The packrat package attempts to re-use R packages whenever possible. Otherwise, return use R's internal tar implementation, which may.If on Windows, look for the system tar and use that if it exists.If a TAR environment variable is set, respect that. ![]() Packratĭetermines the tar binary to use with the following heuristic: Packrat uses the tar command to extract downloaded packages.
