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 "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. See use_cache for details on how the R dataverse package uses disk and session caches to improve network performance.

Value

A list of class “dataverse_dataset_version”.

Details

This returns a list of objects of all versions of a dataset, including metadata. This can be used as a first step for retrieving older versions of files or datasets.
