UpdateQualificationScore: Update a worker's score for a QualificationType

Description

Update a worker's score for a QualificationType that you created. Scores for built-in QualificationTypes (e.g., location, worker statistics) cannot be updated.

Usage

UpdateQualificationScore(qual, workers, values = NULL, increment = NULL, 
                         verbose = getOption('MTurkR.verbose', TRUE), ...)

Arguments

qual

A character string containing a QualificationTypeId.

workers

A character string containing a WorkerId, or a vector of character strings containing multiple WorkerIds.

values

A character string containing an integer value to be assigned to the worker, or a vector of character strings containing integer values to be assigned to each worker (and thus must have length equal to the number of workers).

increment

An optional character string specifying, in lieu of values, the amount that each worker's current QualfiicationScore should be increased.

verbose

Optionally print the results of the API request to the standard output. Default is taken from getOption('MTurkR.verbose', TRUE).

...

Additional arguments passed to request.

Value

• A dataframe containing the QualificationTypeId, WorkerId, Qualification score, and whether the request to update each was valid.

Details

A function to update the Qualification score assigned to one or more workers for the specified custom QualificationType. The simplest use is to specify a QualificationTypeId, a WorkerId, and a value to be assigned to the worker. Scores for multiple workers can be updated in one request. Additionally, the increment parameter allows you to increase (or decrease) each of the specified workers scores by the specified amount. This might be useful, for example, to keep a QualificationType that records how many of a specific style of HIT a worker has completed and increase the value of each worker's score by 1 after they complete a HIT. updatequalscore() is an alias.
