How to do a phylogenetic analyses in R?

All organisms are linked together by the tree of life. We can use this tree along with trait data, to understand many aspects of biology: does specialization lead to increased speciation? do body size and brain size coevolve? how have genome sizes changed over time? and more. R has many functions to address such questions. This website has tutorials on how to do these analyses in R and an overview of what is available in R.
