A metric that counts the occurrence of the same adjacent pairs. Only horizontal and vertical pairs are counted.
Arguments
- design_matrix
A matrix representing the design
- pair_mapping
A named vector of pairs generated from create_pair_mapping
Value
Named list containing:
nb - Table of pairs of items and their number of occurrence
max_nb - The highest number of occurrence
max_pairs - Vector of pairs of items with the highest number of occurrence
Examples
design_matrix <- matrix(c(1, 2, 2, 1, 3, 3, 1, 3, 3), nrow = 3, ncol = 3)
calculate_nb(design_matrix)
