Usage

Arguments
- lineup_vec

omitted from the dataframe due to lack of selection by all mock witnesses.
It functions as a check that the total number of lineup members is accurate.
Examples
# Choices of 50 mock witnesses to a 6-member lineup: passes silently
set.seed(1)
lineup_vec <- sample(1:6, 50, replace = TRUE)
