simNull: Simulate OTU table with null group-level effect for...

In smvargas/PERMANOVA: Power estimation for microbiome studies using pairwise distances and PERMANOVA.

Description

Within-group distances simulated from OTU number and depth of subsampling (rarefying); no group-level differences.

Usage

simNull(group_size_vector = c(100, 100, 100), otu_number = 1000,
  sequence_depth = 1, rare_depth = 0.5)

Arguments

group_size_vector	numeric vector representing subjects per exposure/intervention group
otu_number	number of simulated OTUs
sequence_depth	number of sequence counts per OTU bin
rare_depth	proportion of sequence counts to retain after subsampling

Details

For weighted analysis, specify a sequence depth greater than 1; for unweighted analyses, sequence depth is 1 (default).

Value

two-dimensional matrix OTU table, with row and column names to suit downstream analysis
