Add or update a file in a dataset

Add or update a file in a dataset. For most applications, this is the recommended function to upload your own local datasets to an existing Dataverse dataset. Uploading requires a Dataverse API Key in the key variable.

add_dataset_file(
  file,
  dataset,
  description = NULL,
  key = Sys.getenv("DATAVERSE_KEY"),
  server = Sys.getenv("DATAVERSE_SERVER"),
  ...
)

update_dataset_file(
  file,
  dataset = NULL,
  id,
  description = NULL,
  force = TRUE,
  key = Sys.getenv("DATAVERSE_KEY"),
  server = Sys.getenv("DATAVERSE_SERVER"),
  ...
)

Arguments

file

A character string for the location path of the file to be uploaded.

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().

description

Optionally, a character string providing a description of the file.

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.

id

An integer specifying a file identifier; or, if doi is specified, a character string specifying a file name within the DOI-identified dataset; or an object of class “dataverse_file” as returned by dataset_files.

force

A logical indicating whether to force the update even if the file types differ. Default is TRUE.

Value

add_dataset_file returns the new file ID. It also uploads the file to the dataset.

Details

From Dataverse v4.6.1, the “native” API provides endpoints to add and update files without going through the SWORD workflow. To use SWORD instead, see add_file. add_dataset_file adds a new file to a specified dataset.

update_dataset_file can be used to replace/update a published file. Note that it only works on published files, so unpublished drafts cannot be updated - the dataset must first either be published (publish_dataset) or deleted (delete_dataset).

Examples

if (FALSE) { # \dontrun{
meta <- list()
ds <- create_dataset("mydataverse", body = meta)


# Upload RDS dataset saved to local
saveRDS(mtcars, tmp <- tempfile(fileext = ".rds"))
f <- add_dataset_file(tmp, dataset = ds, description = "mtcars")

# Publish dataset
publish_dataset(ds)

# Update file and republish
saveRDS(iris, tmp)
update_dataset_file(tmp, dataset = ds, id = f,
                    description = "Actually iris")
publish_dataset(ds)

# Cleanup
unlink(tmp)
delete_dataset(ds)
} # }
