group.rich: Barplot Of Richness For Each Level Of A Given Metadata...

In RAM: R for Amplicon-Sequencing-Based Microbial-Ecology

Description

This function first use specpool to estimate the extrapolated species richness in a species pool (levels of metadata variable), and the number of unobserved species, then do a barplot.

Usage

group.rich(otu, meta, factor, file=NULL, ext=NULL, 
           width=8, height=8)

Arguments

otu	an OTU table.
meta	the metadata table to be used (must have same samples as data.
factor	a character string. Must be one of the metadata variables.
file	optional. Filename that the plot to be saved to.
ext	optional. Filename extension, type of image to be saved.
width	an integer. Filter OTU table by counts.
height	an integer. Filter OTU table by counts.

Value

This function returns a barplot of species richness for a given metadata variable.
