GetAssignment: Get Assignment(s)

Description

Get an assignment or multiple assignments for one or more HITs (or a HITType) as a dataframe.

Usage

GetAssignment(assignment = NULL, hit = NULL, hit.type = NULL, status = NULL, 
              return.all = FALSE, pagenumber = "1", pagesize = "10", 
              sortproperty = "SubmitTime", sortdirection = "Ascending", 
              response.group = NULL, keypair = credentials(),
              print = getOption('MTurkR.print'),
              browser = getOption('MTurkR.browser'),
              log.requests = getOption('MTurkR.log'),
              sandbox = getOption('MTurkR.sandbox'),
              return.assignment.dataframe = TRUE,
              validation.test = getOption('MTurkR.test'))

Arguments

assignment

An optional character string specifying the AssignmentId of an assignment to return.

hit

An optional character string specifying the HITId whose assignments are to be returned, or a vector of character strings specifying multiple HITIds all of whose assignments are to be returned.

hit.type

An optional character string specifying the HITTypeId (or a vector of HITTypeIds) of one or more HITs whose assignments are to be returned.

status

An optional character string (of Approved,Rejected,Submitted), specifying whether only a subset of assignments should be returned. If NULL, all assignments are returned (the default). Only ap

return.all

If TRUE, all available assignments are returned. Otherwise, only assignments falling within the specified pagenumber and pagesize search results are returned.

pagenumber

An optional character string indicating which page of search results should be returned (only appropriate when specifying a single HITId). Most users can ignore this.

pagesize

An optional character string indicating how many search results should be returned by each request (only appropriate when specifying a single HITId), between 1 and 100. Most users can ignore this.

sortproperty

One of AcceptTime, SubmitTime, AssignmentStatus. Ignored if return.all=TRUE. Most users can ignore this.

sortdirection

Either Ascending or Descending. Ignored if return.all=TRUE. Most users can ignore this.

response.group

An optional character string (or vector of character strings) specifying what details to return. If assignment is specified, response.group can include any of Request, Minimal, Assignment

keypair

A two-item character vector containing an AWS Access Key ID in the first position and the corresponding Secret Access Key in the second position. Set default with credentials.

print

Optionally print the results of the API request to the standard output. Default is TRUE.

browser

Optionally open the request in the default web browser, rather than opening in R. Default is FALSE.

log.requests

A logical specifying whether API requests should be logged. Default is TRUE. See readlogfile for details.

sandbox

Optionally execute the request in the MTurk sandbox rather than the live server. Default is FALSE.

return.assignment.dataframe

A logical specifying whether the Assignment dataframe should be returned. Default is TRUE.

validation.test

A logical specifying whether only the pre-request checks should be conducted and the request URL returned (without executing the request). Default is FALSE.

Value

• Optionally a dataframe containing Assignment data, including workers responses to any questions specified in the question parameter of the CreateHIT function.

Details

This function returns the requested assignments. The function must specify an AssignmentId xor a HITId xor a HITTypeId. If an AssignmentId is specified, only that assignment is returned. If a HIT or HITType is specified, default behavior is to return all assignments through a series of sequential (but invisible) API calls meaning that returning large numbers of assignments (or assignments for a large number of HITs in a single request) may be time consuming. GetAssignments(), assignment(), and assignments() are aliases.
