degl: Construct matrix of exponent vectors.

In peterrobertcurtis/SSM: Fit and Analyze Smooth Supersaturated Models

Description

This function is called by fit.ssm when it needs to construct the matrix of exponent vectors stored in the basis slot.

Usage

degl(d, N, exclude = list())

Arguments

d	A number. This determines the number of columns in the output matrix
N	A number. This determines the number of rows in the output matrix.
exclude	(optional) A list of integer vectors. If this argument is provided, the generated matrix will not contain any rows which are only non-zero in the columns specified by any of the vectors in the list.

Details

The algorithm works by repeated calls to comb to generate all possible exponent vectors of a given degree until N vectors have been generated. Any generated vector is checked to make sure that it's non-zero entries do not match a vector provided in exclude before being added to the output matrix.
