CRABS: Congruent Rate Analysis in Birth-death Scenarios

A package for investigating and visualizing the congruence class (Louca & Pennell 2020) of a phylogenetic birth-death model. Previously, this package went by the acronym ACDC.

Installation:

The stable version can be installed from CRAN:

install.packages("CRABS")

The developmental version can be installed from the github repository. The package devtools makes this convenient:

install.packages("devtools")
library(devtools)
install_github("afmagee/CRABS")

Documentation

There is documentation for each function in R (type ?CRABS in the R-console), as well as a long-form vignette with an example workflow.
