Extract tip states from a phylod object
get_sse_tip_states(phylod, sse_model = "musse")an integer vector of tip states, as expected by SSE models
A phylo4d object from the package phylobase containing
phylogenetic and endemicity data for each species.
either "musse" (default) or "geosse". MuSSE expects state values 1, 2, 3, which here we encode as "not_present", "endemic", "nonendemic", respectively. GeoSSE expects trait values 0, 1, 2, with 0 the widespread state (here, "nonendemic"), and 1 and 2 are "not_present" and "endemic", respectively.
