A function to automatically build a photo roster for data collection

Description

This is a helper function to plot the roster. Posters are saved in the "Survey" folder.

Usage

build_roster(
  path,
  pattern = ".jpg",
  start = 1,
  stop = 3,
  seed = 1,
  n_panels = 4,
  n_rows = 5,
  n_cols = 8,
  ordered = NULL,
  size_out = 1000,
  chip_width = 300,
  asr = 1.618,
  width = 2.5
)

Arguments

path	Full path to main folder.
pattern	File extension of photos. Should be ".jpg" or ".JPG".
start	Location of start of PID in file name. If files are saved as "XXX.jpg" for example, this is 1.
stop	Location of end of PID in file name. If files are saved as "XXX.jpg" for example, this is 3.
seed	A seed for the random number generator to sort the order of photos in the array. This should match the seed used to make the survey.
n_panels	Number of frames/panels/blocks of photos to be output. I use four big panels and randomize order at each game.
n_rows	Number of rows per panel. With 7cm x 10cm photos, I use five rows of photos per panel.
n_cols	Number of rows per panel. With 7cm x 10cm photos, I use six to eight cols of photos per panel.
ordered	A list of IDs if photograph order is to be explicilty coded. This overwrites random sorting, otherwise NULL.
size_out	Width of standardized photos (pixels).
chip_width	Width at which reference chip should be printed (pixels).
asr	Aspect ratio of each photo.
width	Width at which each photo on the poster should be printed (inches).
