runSampleExperiment {MLDS}R Documentation

Start and run a Difference Scale Experiment

Description

Runs a difference scaling experiment displaying stimuli with the function DiplayTrial defined by the function DefineStimuli.

Usage

runSampleExperiment(DisplayTrial, DefineStimuli, NumTrials = NULL,
        DisplaySize = 7.5, aspect = 1, ...)

Arguments

DisplayTrial character giving the name of a function to display a trial with quadruple of stimuli.
DefineStimuli character giving the name of a function that defines the set of stimuli from which quadruples are drawn.
DisplaySize numeric giving the overall size of the display on the screen.
NumTrials integer giving the number of trials to display. If NULL (the default), the number is computed on the basis of the size of stimulus set designated by DefineStimuli.
... currently unused
aspect numeric giving the height/width ratio of the display on the screen.

Details

This function is to demonstrate how to run a difference scaling experiment. Two helper functions DisplayOneTrial and DefineMyScale permit running the perception of correlation experiment, sample data from which are provided as datasets, (see kk).

Value

An object of class ‘mlds.df’ is returned. It inherits from ‘data.frame’ and has attributes ‘stimulus’ and ‘invord’. See kk for an example.
