# phylotypr: an R package for classifying DNA sequences

## TL;DR

The phylotypr R package uses a Bayesian algorithm to classify DNA sequences into taxonomic groups, with supporting databases from major projects.

## Contribution

A new R package and data companion for taxonomic classification of DNA sequences using Bayesian methods and curated databases.

## Key findings

- phylotypr implements a naive Bayesian classifier for DNA sequences.
- The phylotyprrefdata package provides multiple taxonomic databases from RDP, SILVA, and greengenes.

## Abstract

The phylotypr R package implements the popular naive Bayesian classification algorithm that is frequently used to classify 16S rRNA and other gene sequences to taxonomic lineages. A companion data package, phylotyprrefdata, also provides numerous versions of taxonomic databases from the Ribosomal Database Project, SILVA, and greengenes.
