| build_survey | R Documentation | 
This function allows you to speed up data collection and photo randomization. Simply set a path to the main folder. Set the number of panels, and the number of rows and cols per panel. Then run the function. This function relies on 'xtable' to create a survey tool, and compile to PDF using LaTeX. The user must have a LaTeX build on the system path.
build_survey(
  path,
  pattern = ".jpg",
  start = 1,
  stop = 3,
  n_panels = 4,
  n_rows = 5,
  n_cols = 8,
  seed = 1,
  ordered = NULL
)
| 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. | 
| 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 cols per panel. With 7cm x 10cm photos, I use six to eight cols of photos per panel. | 
| seed | A seed for the random number generator to sort the order of photos in the array. | 
| ordered | A list of IDs in explicit order. Can be used to overide random sorting. |
