dataset_versions function

Dataset versions

View versions of a dataset

dataset_versions(
  dataset,
  key = Sys.getenv("DATAVERSE_KEY"),
  server = Sys.getenv("DATAVERSE_SERVER"),
  ...
)

Arguments

• dataset: A character specifying a persistent identification ID for a dataset, for example "doi:10.70122/FK2/HXJVJU". Alternatively, an object of class dataverse_dataset obtained by dataverse_contents().

• key: A character string specifying a Dataverse server API key. If one is not specified, functions calling authenticated API endpoints will fail. Keys can be specified atomically or globally using Sys.setenv("DATAVERSE_KEY" = "examplekey").

• server: A character string specifying a Dataverse server. Multiple Dataverse installations exist, with "dataverse.harvard.edu" being the most major. The server can be defined each time within a function, or it can be set as a default via an environment variable. To set a default, run Sys.setenv("DATAVERSE_SERVER" = "dataverse.harvard.edu")

  or add DATAVERSE_SERVER = "dataverse.harvard.edu in one's .Renviron

  file (usethis::edit_r_environ()), with the appropriate domain as its value.

• ...: Additional arguments passed to an HTTP request function, such as GET, POST, or DELETE.

Returns

A list of class dataverse_dataset_version .
