The basic indval() command will produce a large output of the many values calculated, including Tutorial 12). The output will be assigned to a new name, ‘dist Value The default function returns a list of class ‘indval’ with components: The stride-based function returns a data.frame with the number of clusters in the first column and the mean indicator value in the second. The ‘summary’ function has two options. R/indval.R defines the following functions: indval indval.default indval.stride The coverage value is a generalization of quantity B of IndVal, that applies to a group of indicators instead of a single one.

This package leverages many of the tools available in R for ecology and phylogenetic analysis (vegan, ade4, ape, picante), while also using advanced/flexible graphic systems (ggplot2) to easily produce publication-quality graphics of complex phylogenetic data. phyloseq uses a specialized system of S4 classes to store all related phylogenetic sequencing data as single experiment-level object

Indeed, the indicator value index is the product of two components, called ‘A’ and ‘B’ [Dufr^ene and Legendre, 1997][De C aceres and Legendre, 2009]. This package leverages many of the tools available in R for ecology and phylogenetic analysis (vegan, ade4, ape, picante), while also using advanced/flexible graphic systems (ggplot2) to easily produce publication-quality graphics of complex phylogenetic data.
