Taxmap class

A class designed to store a taxonomy and associated information. This class builds on the taxonomy() class. User defined data can be stored in the list obj$data, where obj is a taxmap object. Data that is associated with taxa can be manipulated in a variety of ways using functions like filter_taxa() and filter_obs(). To associate the items of lists/vectors with taxa, name them by taxon_ids(). For tables, add a column named taxon_id that stores taxon_ids().

Usage
taxmap(..., .list = NULL, data = NULL, funcs = list(),
  named_by_rank = FALSE)
Arguments
...

Any number of object of class hierarchy() or character vectors.

.list

An alternate to the ... input. Any number of object of class hierarchy() or character vectors in a list. Cannot be used with ....

data

A list of tables with data associated with the taxa.

funcs

A named list of functions to include in the class. Referring to the names of these in functions like filter_taxa() will execute the function and return the results. If the function has at least one argument, the taxmap object is passed to it.

named_by_rank

(TRUE/FALSE) If TRUE and the input is a list of vectors with each vector named by ranks, include that rank info in the output object, so it can be accessed by out$taxon_ranks(). If TRUE, taxa with different ranks, but the same name and location in the taxonomy, will be considered different taxa.

Details

To initialize a taxmap object with associated data sets, use the parsing functions parse_tax_data(), lookup_tax_data(), and extract_tax_data().

on initialize, function sorts the taxon list based on rank (if rank information is available), see ranks_ref for the reference rank names and orders

Value

An R6Class object of class taxmap()
