### Description

This is a simple accessor function to make it more convenient to determine the different taxa present for a particular taxonomic rank in a given `phyloseq-class` object.

### Arguments

`physeq` | (Required). `taxonomyTable-class`, or `phyloseq-class`.
`taxonomic.rank` | (Optional). Character. The taxonomic rank to use. Must select from the set indicated by `get_taxa_unique`. Default is to take the first column of the `taxonomyTable` component.
`errorIfNULL` | (Optional). Logical. Should the accessor stop with an error if the slot is empty (`NULL`)? Default `TRUE`.

Character vector. Unique vector of the observed taxa at a particular taxonomic rank
