Simulation Free Stochastic Mapping

Description

SFREEMAP is an analytical approach to obtain accurate, per-branch expectations of numbers of state transitions and dwelling times. It also provides an intuitive way of visualizing the results by integrating over the posterior and summarizing the parameters onto a target reference topology (such as a consensus or MAP tree) provided by the user.

The DESCRIPTION file: This package was not yet installed at build time.
Index: This package was not yet installed at build time.

This package can be used to perform a stochastic mapping in one or more phylogenetic trees, providing as result the expected number of transitions of states and the dwelling times for each branch of the tree.

Afterwards it is possible to analyse the results through charts and plots from tools provided in this package.

The method implemented is based on an article written by Vladimir Minin and Marc Suchard, describing a way to perform analytical stochastic mapping, without requiring to simulations as most methods do. As a result of this, the execution of most functions is really fast.
