The pkg_download_proposal and pkg_installation_proposal classes both have download methods, to downloads package files into a configured directory (see 'Configuration').

Details

They return a pkg_download_result object, which is a data frame (tibble), that adds extra columns to pkg_resolution_result (for pkg_download_proposal) or pkg_solution_result (for pkg_installation_proposal):

  • fulltarget: absolute path to the downloaded file. At most one of fulltarget and fulltarget_tree must exist on the disk.

  • fulltarget_tree: absolute path to a package tree directory. At most one of fulltarget and fulltarget_tree must exist on the disk.

  • download_status: "Had" or "Got", depending on whether the file was obtained from the cache.

  • download_error: error object for failed downloads.

  • file_size: Size of the file, or NA. For installed:: refs, it is NA, and it is also NA for refs that created fulltarget_tree instead of fulltarget.

fulltarget, if it exists, contains a packaged (via R CMD build) source R package. If fulltarget_tree exists, it is a package tree directory, that still needs an R CMD build call.
