divide_probs_by_number_of_options_txt: Divide each type of event by its frequency

In BioGeoBEARS: BioGeography with Bayesian (and Likelihood) Evolutionary Analysis in R Scripts

Description

In a speciation/cladogenesis matrix, the conditional probabilities of each row must sum to 1. This function sums the number of events of each category and scales them accordingly.

Usage

  divide_probs_by_number_of_options_txt(probmat)

Arguments

probmat

A character matrix of probabilities in the form of formulas, not normalized by the sum of each row.

Details

This function returns the strings, which can then be processed in other functions by e.g. find/replace or eval.

Value

probmat A matrix of strings, where each cell contains the parameters describing the conditional probability of that ancestor–>(Left descendant,Right descendant) range inheritance scenario.

Note

Go BEARS!
