labkey.provenance.startRecording: Start a provenance recording

In Rlabkey: Data Exchange Between R and 'LabKey' Server

Start a provenance recording

Description

Function to start a provenance recording session, if successful a provenance recording ID is returned which can be used to add additional steps to the provenance run. Note: this function is in beta and not yet final, changes should be expected so exercise caution when using it.

Usage

labkey.provenance.startRecording(baseUrl=NULL, folderPath, provenanceParams = NULL)

Arguments

baseUrl	a string specifying the baseUrl for the labkey server
folderPath	a string specifying the folderPath
provenanceParams	the provenance parameter object which contains the options to include in this recording step

Details

Function to start a provenance recording. A provenance recording can contain an arbitrary number of steps to create a provenance run, but stopRecording must be called to finish the recording and create the run. If successful this will return a recording ID which is needed for subsequent steps. This is a premium feature and requires the Provenance LabKey module to function correctly.

Value

The generated recording ID which can be used in subsequent steps (or queries that support provenance).
