Description Usage Arguments See Also Examples

On GitHub, a user can upload multiple keys. This function will download the first key by default, but you can change this

1	add_github_user(github_user, email = NULL, vault = NULL, i = 1)

`github_user`	User name on GitHub.
`email`	Email address of the github user. If NULL, constructs an email as `github-<<github_user>>`
`vault`	Vault location (starting point to find the vault). To create a vault, use `create_vault()` or `create_package_vault()`. If this is `NULL`, then `secret` tries to find the vault automatically: If the `secret.vault` option is set to path, that is used as the starting point. Otherwise, if the `R_SECRET_VAULT` environment variable is set to a path, that is used as a starting point. Otherwise the current working directory is used as the starting point. If the starting point is a vault, that is used. Otherwise, if the starting point is in a package tree, the `inst/vault` folder is used within the package. If no vault can be found, an error is thrown.
`i`	Integer, indicating which GitHub key to use (if more than one GitHub key exists).
