Data summarizing the evolution of feeding habits in eels using a 3-level factor as categorical trait

Source: R/datasets_doc.R
eel_cat_3lvl_data.Rd

A list containing feeding habits data of eels mapped on the phylogeny, modeled with geiger::fitDiscrete. This object was obtained with prepare_trait_data(). Initial data was altered arbitrarily to create three categories, adding a "kiss" feeding habit to the initial "bite" and "suction" data. This is NOT real biological data. Please refer to the initial article for real data.

Usage

data(eel_cat_3lvl_data)

Format

A list with 6 elements.

Details

A list of five objects containing information on the evolution of feeding habits in eels. This object was obtained with prepare_trait_data().

  • $densityMaps List of objects of class "densityMap that contains a phylogenetic tree and associated mapping of probability to harbor a given state/range along branches. The list contains one "densityMap per state/range found in the tip_data.

  • $trait_data_type Character string. Record the type of trait data. Here: "categorical".

  • $simmaps List of 100 stochastic mapping simulations for trait evolution. Each element is a "simmap" object (see phytools::make.simmap) representing a possible evolutionary history that fits states observed on tips, infered ACE at internal nodes, and transition rates as estimated from the best fit model.

  • $ace Numerical matrix that record the posterior probabilities of ancestral states/ranges (characters) estimates (ACE) at internal nodes. Rows are internal nodes. Columns are states/ranges. Values are posterior probabilities of each state per node.

  • $best_model_fit List that provides the output of the best fitting model (Here: ER model).

  • $model_selection_df Data.frame that summarizes model comparisons used to select the best fitting model.
