R Documentation

Get taxa without classification

Description

Identifies taxa from a community vector that are absent from a classification table. Returns the names of taxa that do not have a matching entry in the ‘sel_name’ column of the classification table.

Usage

get_taxa_without_classification(vec_community_taxa, data_classification_table)

Arguments

vec_community_taxa

A non-empty character vector of taxon names present in the community data.

data_classification_table

A data frame containing a ‘sel_name’ column with unique taxon names used for classification lookup. Must not contain duplicate values in ‘sel_name’.

Details

Uses ‘dplyr::anti_join()’ to find taxa present in ‘vec_community_taxa’ but absent from the ‘sel_name’ column of ‘data_classification_table’. Duplicate entries in ‘vec_community_taxa’ are collapsed before the comparison, so each unclassified taxon appears only once in the output.

Value

A character vector of taxon names from ‘vec_community_taxa’ that are not found in ‘data_classification_table$sel_name’. Returns an empty character vector if all taxa are classified.
