repeatingInstrumentMethods: Export or Import Repeating Instrument and Events Settings

Description

These methods enable the user to export the existing repeating instrument and event settings, or import new settings to the project.

Usage

exportRepeatingInstrumentsEvents(rcon, ...)
importRepeatingInstrumentsEvents(rcon, data, ...)
# S3 method for redcapApiConnection
exportRepeatingInstrumentsEvents(rcon, ...)
# S3 method for redcapApiConnection
importRepeatingInstrumentsEvents(rcon, data, ...)

Value

exportRepeatingInstrumentsEvents returns a data frame with the columns:

event_name	The unique event name.
form_name	The form name, as given in the second column of the Meta Data
custom_form_label	A custom display string for the repeating instrument/event

importRepeatingInstrumentsEvents invisibly returns the number of rows imported.

Arguments

rcon

A redcapConnection object.

data

data.frame. For classical projects, it must have the columns form_name and custom_form_label. Longitudinal projects also require a column for event_name.

...

Arguments to pass to other methods

Functions

• exportRepeatingInstrumentsEvents(): Export repeating instruments and events.

• importRepeatingInstrumentsEvents(): Import repeating instruments and events.

Details

Repeating events (as opposed to repeating instruments) are provided as a row of data where the form_name column is NA.

It is not possible to update the has_repeating_instruments_or_events property of the project through importProjectInformation. Enabling of repeating instruments and events must be done through the GUI.

Although the API does not provide a delete method, it is possible to remove settings by doing an import that excludes the settings that are to be deleted. All settings can be cleared by executing importRepeatingInstrumentsEvents(rcon, REDCAP_REPEAT_INSTRUMENT_STRUCTURE).
