randomize_by_rows: Randomize by Rows

In jfq3/QsNullModels: My null model functions

Description

This function randomizes a binary matrix by shuffling the values in rows using sampling probabilities specified in vector w. It is similar to Sim4 but has the advantage that the user may specify w instead of having it calculated from the column sums.

Usage

randomize_by_rows(com, w, rename=FALSE)

Arguments

com	A binary community matrix with samples as rows and taxaa as columns.
w	Sampling weights in a vector of length equal to row length in com.
rename	A logical indicating whether or not samples should be renamed.

Details

The number of non-zero entries in w must be at least the maximum number of non-zero entries in a row of com (max(rowSums(com)).

Value

A randomized binary matrix.
