get_dataverse function

Get Dataverse

Retrieve details of a Dataverse

get_dataverse(
  dataverse,
  key = Sys.getenv("DATAVERSE_KEY"),
  server = Sys.getenv("DATAVERSE_SERVER"),
  check = TRUE,
  ...
)

dataverse_contents(
  dataverse,
  key = Sys.getenv("DATAVERSE_KEY"),
  server = Sys.getenv("DATAVERSE_SERVER"),
  ...
)

Arguments

• dataverse: A character string specifying a Dataverse name or an object of class dataverse .

• 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.

• check: A logical indicating whether to check that the value of dataverse is actually a numeric

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

Returns

A list of class dataverse .

Details

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.

Examples

## Not run:

# https://demo.dataverse.org/dataverse/dataverse-client-r
Sys.setenv("DATAVERSE_SERVER" = "demo.dataverse.org")

# download file from:
dv <- get_dataverse("dataverse-client-r")

# get a dataset from the dataverse
(d1 <- get_dataset(dataverse_contents(dv)[[1]]))

# download a file using the metadata
get_dataframe_by_name("roster-bulls-1996.tab", d1$datasetPersistentId)
