weight.NtoN: Convert Bits to Weights Matrix

In tpq/amalgam: Amalgamation-Based Dimension Reduction of Compositional Data

Description

This function builds a weights matrix from a binary vector. The resultant weights matrix with have n.amalgams columns and a number of rows based on the size of the binary vector. The resultant weights matrix will have rows that sum to 1. It is possible for row sums or column sums to equal 0.

Usage

weight.NtoN(codon, n.amalgams)

Arguments

codon	A binary vector.
n.amalgams	The number of columns in the weights matrix.

Details

The interpretation of this weights matrix is that each component can contribute to multiple amalgam nodes, but must contribute an equal amount to each node.

Examples

# For 2 amalgams, read as "node 2", "node 1+2", "node 1", "node 0"
weight.NtoN(c(0,1,1,1,1,0,0,0), 2)
