parse_phyloseq: Convert a phyloseq to taxmap

In metacoder: Tools for Parsing, Manipulating, and Graphing Taxonomic Abundance Data

Convert a phyloseq to taxmap

Description

Converts a phyloseq object to a taxmap object.

Usage

parse_phyloseq(obj, class_regex = "(.*)", class_key = "taxon_name")

Arguments

obj	A phyloseq object
class_regex	A regular expression used to parse data in the taxon names. There must be a capture group (a pair of parentheses) for each item in class_key. See parse_tax_data for examples of how this works.
class_key	('character' of length 1) The identity of the capturing groups defined using 'class_regex'. The length of 'class_key' must be equal to the number of capturing groups specified in 'class_regex'. Any names added to the terms will be used as column names in the output. At least one '"taxon_name"' must be specified. Only '"info"' can be used multiple times. Each term must be one of those described below: * 'taxon_name': The name of a taxon. Not necessarily unique, but are interpretable by a particular 'database'. Requires an internet connection. * 'taxon_rank': The rank of the taxon. This will be used to add rank info into the output object that can be accessed by 'out$taxon_ranks()'. * 'info': Arbitrary taxon info you want included in the output. Can be used more than once.

Value

A taxmap object
