plot_fit_env function

Plot speciation, extinction & net diversification rate functions of a fitted environmental model

Plot estimated speciation, extinction & net diversification rates as a function of the environmental data and time

plot_fit_env(fit.env, env_data, tot_time)

Arguments

• fit.env: an object of class 'fit.env', output of the 'fit_env' function
• env_data: environmental data, given as a data frame with two columns. The first column is time, the second column is the environmental data (temperature for instance).
• tot_time: the age of the phylogeny (crown age, or stem age if known). If working with crown ages, tot_time is given by max(node.age(phylo)$ages).

Returns

Plots representing how the estimated speciation, extinction & net diversification rate functions vary as a function of the environmental data & time
