Webb12 apr. 2024 · Since the efficient way to do this using an R "phylo" object is to reorder the tree in a post-order fashion just once – regardless of how many characters we want to analyze – I decided to split my code into two functions: one (called Fitch) that performs the algorithm on a post-order sorted "phylo" object; and a second (called pscore) that will do … WebbThis function performs the simulation-based phylogenetic ANOVA of Garland et al.

Then, we repeated this for each predictor variable keeping it at its mean value for continuous variables. WebbfitMk function in the package phytools, based on information theoreti-cal measures. Description Creates a model selection table based on either AIC or AICc for categorical trait evolution models fit using the fitMk() function in the phytools package. Usage WebbWe conducted an ancestral state reconstruction (ASR) of food plants (here the term ‘food plants’ refer to plants fed upon by caterpillars in nature) using SIMMAP in the R v. 3 package phytools with the symmetrical (‘SYM’) model and 10,000 simulations (Bollback 2006, Revell 2011, R Core Team 2024). cyclical view of time
