Package CRAN Repository Resource Class

Source: R/class_resource.R
cran_repo_resource.Rd

A reference to a listing in CRAN. CRAN Resources must be from one of the repositories listed in utils::getCRANmirrors(). To assert that a new url is also a CRAN mirror, please follow instructions in utils::getCRANmirrors().

Usage

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

Arguments

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.
