CreateClassObject: Create class object

Description

This function returns names of internode intervals, named descendants of each node, and a class object formatted in a way that can be passed to CreateGeobyClassObject

Usage

CreateClassObject(map,rnd=5,return.mat=FALSE)

Value

a list with the following components:

class.object

a list of matrices specifying the state of each branch during each internode interval (see Details)

times

a vector containing the time since the root of the tree at which nodes or changes in biogeography occur (used internally in other functions)

spans

a vector specifying the distances between times (used internally in other functions)

Arguments

map

stochastic map from make.simmap in phytools

rnd

integer indicating the number of decimal places to which times should be rounded (default value is 5) (see round)

return.mat

logical indicating whether to return simmap in a format to be passed to other internal functions (usually FALSE)

Author

Jonathan Drury

Details

This function formats the class object so that it can be correctly passed to the numerical integration performed in fit_t_comp_subgroup.
