Filter Rare Taxa

Usage

filter_rare_taxa(data = NULL, minimal_proportion = 0.01)

Arguments

data	A data frame containing taxon abundance data. Must include a column named ‘pollen_prop’ with numeric proportions or abundances.
minimal_proportion	Numeric value between 0 and 1 specifying the minimum proportion threshold for retaining taxa. Default is 0.01 (1

A filtered data frame containing only taxa that meet or exceed the minimal proportion threshold. Preserves all original columns.

Filters out rare taxa from community data based on a minimum proportion threshold. Only taxa meeting or exceeding the threshold are retained.

The function validates that minimal_proportion is a numeric value between 0 and 1. After filtering, it checks that at least one taxon remains in the dataset. If no taxa meet the threshold, an error is raised suggesting the threshold may be too high.
