Description

Create a matrix of items

Usage

mnrva_item_matrix(n_items = 5, vec_length = 10, all_unique = FALSE,
  max_iteration = 5)

Arguments

n_items	integer number of items to create (rows)
vec_length	integer (even) number of features in each item, or vector length
all_unique	logical default is FALSE, setting to TRUE ensures that all item entries are unique. Currently this is accomplished by brute force (iterating and checking until the entire matrix).

Details

This functions creates a matrix of items. Each item is a randomly permuted vector of 1s and -1s.

Value

matrix items across rows, and features across columns

Examples

mnrva_item_matrix(n_items = 5, vec_length = 10)
mnrva_item_matrix(n_items = 5, vec_length = 10, all_unique = TRUE)
