bears_3param_standard_fast: 3-parameter model, adding j (founder-event speciation)
In BioGeoBEARS: BioGeography with Bayesian (and Likelihood) Evolutionary Analysis in R Scripts

Description Usage Arguments Value Note Author(s) References See Also Examples

This implements a 3-parameter model, basically LAGRANGE or bears_2param_standard_fast, but with a parameter j controlling the relative weight of "founder-event speciation" (Matzke (2012)) versus vicariance+sympatric speciation (which are mandated in LAGRANGE and bears_2param_standard_fast.

    geogfn = "Psychotria_geog.data", max_range_size = NULL,
    num_cores_to_use = NULL)

`trfn`	The filename of the phylogenetic tree, in NEWICK format (http://evolution.genetics.washington.edu/phylip/newicktree.html). Tipnames should match the names in geogfn. See `read.tree` in APE for reading in phylogenetic trees.
`geogfn`	A PHYLIP-style file with geographic range data (see `getranges_from_LagrangePHYLIP`) for each tipname. This is the same format used by C++ LAGRANGE (SmithRee2010_CPPversion).
`max_range_size`	The maximum rangesize, in number of areas. Having a smaller maximum range size means that you can have more areas (the size of the state space is greatly reduced; see `numstates_from_numareas`.
`num_cores_to_use`	If >1, parallel processing will be attempted. Note: parallel processing via `library (parallel)` will work in Mac command-line R, but not in Mac GUI `R.app`.
