# S3 method for redcapApiConnection
exportMetaData(rcon, fields = NULL,
forms = NULL, error_handling = getOption("redcap_error_handling"), ...)
A REDCap connection object as generated by redcapConnection.
Arguments to be passed to other methods.
A character vector of field names for which the metadata is to be retrieved.
A character vector of forms for which the metadata is to be
retrieved. Note that if a form name is given, all of the fields on that form
will be returned, regardless of whether it is included in fields
or
not. Be careful to use the form names in the second column of the data
dictionary, and not the display names shown on the webpage.
An option for how to handle errors returned by the API.
see redcap_error
This function allows you to export the metadata for a project
5.8.2+ (and earlier, but we don't know how much earlier)
The API doesn't respond to the fields
and forms
arguments. It
always returns the full data dictionary.
A record of this export is placed in the REDCap logging page, but the file that is exported is not stored in the database.
This functionality was originally developed by Jeffrey Horner in the redcap
package.
