paleocoords: paleocoords

In macroecology/mapast: Paleogeography Combined with Spatial Paleobiodiversity

Description

Calculating the paleocoordinates of the fossil data. Either calculating timebins by looking at the early_age and late_age column, taking the rounded average age (avg_age) of the fossils or by using user defined time bins.

Usage

paleocoords(data, time = "automatic", timevector = NULL, 
                        stepsize = 10, model = "SETON2012")

Arguments

data	data.frame. Fossil occurrences data.
time	character. Defines how the reconstruction time is specified. Can be "automatic", "average" or "timevector". By default time = "automatic".
timevector	vector. The borders of the time bins. Not allowed to be NULL if time = "timevector".
stepsize	numeric. The stepsize of the time bins if time = "automatic". By default stepsize = 10.
model	character. The model the map should be created with. "SETON2012" (default), "MULLER2016", "GOLONKA", "PALEOMAP" or "MATTHEWS2016".

Value

data.frame

                         model = "SETON2012")
