## Aggregate Taxa

### Description

Summarize phyloseq data into a higher phylogenetic level.

### Usage

    aggregate_taxa(x, level, verbose = FALSE)

### Arguments

`x` | `phyloseq-class` object
`level` | Summarization level (from `rank_names(pseq)`)
`verbose` | verbose

### Details

This provides a convenient way to aggregate phyloseq OTUs (or other taxa) when the phylogenetic tree is missing. Calculates the sum of OTU abundances over all OTUs that map to the same higher-level group. Removes ambiguous levels from the taxonomy table. Returns a phyloseq object with the summarized abundances.

### Value

Summarized phyloseq object
