package_sources(cran = NULL, repos = NULL, github = NULL,
  local = NULL, expire = NULL, local_drat = NULL, data = NULL,
  spec = NULL)

`cran`	A single URL for the CRAN repo to use. If `NULL`, then this will use the rstudio mirror.
`repos`	A character vector of additional repositories to use. Repositories of the form `drat://username` will be translated to a drat repository hosted on github (e.g., `https://username.github.io/drat`)
`github`	A vector of github package specifications (e.g., username/password). The full syntax as implemented in `parse_github_repo_spec` is supported (packages in subdirectories, or referencing a particular branch, commit or tag).
`local`	A character vector of local files to include. Can be directories or built packages (source or binary)
`expire`	Optional period, in days, to expire the local copy of the package. If specified, then if a package was downloaded more than`expire` days ago when the local copy is checked, a new version will be downloaded. Can be a fractional value (e.g., `expire = 0.04` for an expiry of around an hour).
`local_drat`	Optional location to cache downloaded packages, when `github` or `local` packages are used. If not given, this can be set at any time by setting the `local_drat` element of the returned element. If not given by the time that the packages need to be downloaded then a session-specific temporary directory will be used.
`data`	An object of class `package_sources_list`, created by running the `as_list()` method of a `package_sources` object. This is useful for serialisation without saving references to `provisionr`.
`spec`	Raw entries of the form `<type>::<user>/<repo>...`
