runSampleExperiment {MLDS} | R Documentation |
Runs a difference scaling experiment displaying stimuli with the function DiplayTrial
defined by the function DefineStimuli
.
runSampleExperiment(DisplayTrial, DefineStimuli, NumTrials = NULL, DisplaySize = 7.5, aspect = 1, ...)
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. |
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
).
An object of class ‘mlds.df’ is returned. It inherits from ‘data.frame’ and has attributes ‘stimulus’ and ‘invord’.
See kk
for an example.
