Import metadata (i.e., data dictionary) into a project. Because of this method's destructive nature, it works for only projects in Development status.

redcap_metadata_write(
  ds,
  redcap_uri,
  token,
  verbose = TRUE,
  config_options = NULL
)

Arguments

ds

The base::data.frame() to be imported into the REDCap project. Required.

redcap_uri

The URI (uniform resource identifier) of the REDCap project. Required.

token

The user-specific string that serves as the password for a project. Required.

verbose

A boolean value indicating if messages should be printed to the R console during the operation. The verbose output might contain sensitive information (e.g. PHI), so turn this off if the output might be visible somewhere public. Optional.

config_options

A list of options to pass to httr::POST() method in the 'httr' package. See the details in redcap_read_oneshot() Optional.

Value

Currently, a list is returned with the following elements:

  • success: A boolean value indicating if the operation was apparently successful.

  • status_code: The http status code of the operation.

  • outcome_message: A human readable string indicating the operation's outcome.

  • field_count: Number of fields imported.

  • elapsed_seconds: The duration of the function.

  • raw_text: If an operation is NOT successful, the text returned by REDCap. If an operation is successful, the raw_text is returned as an empty string to save RAM.
