Source: R/demo_stim.R
demo_stim.Rd

A convenience function to get demo stimuli. See the Details below for citation and license info.

Usage

demo_stim(pattern = NULL)

demo_tems(pattern = NULL)

demo_unstandard(pattern = NULL)

Arguments

pattern

Vector of patterns to use to search for files, or a vector of image indices (e.g., 1:4 selects the first 4 images and their templates)

Value

list of stimuli

Details

  • demo_stim(): two composite faces with frl delineations; 500x500 pixels

  • demo_tems(): an image with 5 different delineations; 675x900 pixels

  • demo_unstandard(): a set of 10 composite faces with frl delineations; rotated, resized, and cropped so face position is not standard and each image is a different size (444 to 645 pixels)
