A character string specifying a Dataverse name or an object of class “dataverse”.
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")
.
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.

get_dataverse
function retrieves basic information about a Dataverse from a Dataverse server. To see the contents of the Dataverse, use dataverse_contents
instead. Contents might include one or more “datasets” and/or further Dataverses that themselves contain Dataverses and/or datasets. To view the file contents of a single Dataset, use get_dataset
.
