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

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.

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.
