2 Installation

To get started with exploring congruence classes, you need to have our package CRABS installed. First, make sure that you have a recent version of R installed. You can install the stable version of CRABS from CRAN:

install.packages("CRABS")

We host the developmental version of CRABS on github. If you don’t already have it, the devtools R-package makes it easy to install directly from github. Using devtools makes it easy to install CRABS directly from GitHub.

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

You can then load the CRABS package using the library function:

library(CRABS)

Now you are ready to use CRABS to explore congruence classes in macroevolutionary diversification rates.
