breakaway

R-CMD-check Coverage status

Understanding the drivers of microbial diversity is an important frontier of microbial ecology, and investigating the diversity of samples from microbial ecosystems is a common step in any microbiome analysis.

breakaway is the premier package for statistical analysis of microbial diversity. breakaway implements the latest and greatest estimates of richness, as well as the most commonly used estimates.

DivNet is a package by the breakaway authors for estimating Shannon diversity, and other diversity indices. breakaway focuses on richness while DivNet focuses on Shannon, Simpson, and other alpha diversities as well as some beta diversity indices. Check it out!

Citing breakaway

The R package breakaway implements a number of different richness estimates. Please cite the following if you use them:

Installation

You can install breakaway from github by running:

install.packages("devtools")
devtools::install_github("adw96/breakaway")

breakaway is actively maintained and continually expanding and developing its scope! Is there a method you would like to have implemented in breakaway? Submit a pull request or contact the maintainer!

Do you have a request for us? Let us know! We want folks to use breakaway and are committed to making it as easy to use as possible.

Do you have a question? Check out the above documentation list, then shoot us an email or open a Discussion. We receive a lot of emails from users, so we try to answer questions on the Wiki rather than responding to everyone individually.
