Package Repository Resource Class

A reference to a listing in an R package repository.

Usage

repo_resource(
  package = NA_character_,
  version = NA_character_,
  id = next_id(),
  md5 = NA_character_,
  repo = character(0)
)

package: character(1L) Package name. Optional, but should be provided if possible.
version: character(1L) Package version, provided as a string.
id: integer(1L) optional id used for tracking resources throughout execution. Generally not provided directly, as new objects automatically get a unique identifier. For example, the package source code from a repo_resource() may be downloaded to add a source_archive_resource() and add it to a new multi_resource(). Because all of these represent the same package, they retain the same id. Primarily the id is used for isolating temporary files.
md5: character(1L) md5 digest of the package source code tarball. This is not generally provided directly, but is instead derived when acquiring resources.
repo: character(1L) The repository url from which the package is to be sourced.
