View source: R/funDataMethods.R

Description

This function takes an arbitrary number K of integer values n_1,…, n_K and creates a data frame with all combinations from 1:n_k, where the first column (taking values from 1 to n_1) varies slowest and the last column (())taking values from 1 to n_K) varies fastest. Internally, this function depends on expand.grid
