Global Options

The following global options control package behavior:

• Rdatasets_cache: Logical

  • Whether to cache downloaded data and index for faster subsequent access. Default: TRUE. Please keep this option TRUE as it makes repeated access faster and avoids overloading the Rdatasets server. Only set to FALSE if local memory is severely limited.

  • Ex: 'options(Rdatasets_cache = TRUE)“

• Rdatasets_class: String

  • Output class of the returned data. One of "data.frame" (default), "tibble", or "data.table". Default: "data.frame". Requires the respective packages to be installed for "tibble" or "data.table" formats.

  • Ex: options(Rdatasets_class = "tibble")

• Rdataset_path: String.

  • Base URL for the Rdatasets archive. Default: "https://vincentarelbundock.github.io/Rdatasets/". Advanced users can set this to use a different mirror or local copy.

  • Ex: options(Rdataset_path = "https://vincentarelbundock.github.io/Rdatasets/")
