expand.int: Function to expand integers to a grid of indices

In funData: An S4 Class for Functional Data

Function to expand integers to a grid of indices

Description

This function takes an arbitrary number K of integer values n_1,\ldots, 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

Usage

expand.int(...)

Arguments

...	An arbitrary number of integer values.

Value

A dataframe with the same number of columns as integers supplied and containing all combinations of indices from 1 to the given integers. If no number is supplied, the function returns NULL.

Examples

# For two integers
funData:::expand.int(2,5) # first column varies slowest

# For three integers
funData:::expand.int(2,3,4)
