Models taphonomy by combining the change in taphonomic conditions with the preservation potential as a function of taphonomic conditions to determine how preservation potential changes. This is then used to systematically remove (thin) the event data using thin/ remove specimens from the pre_paleoTS object using prob_remove.
Arguments
- x
event type data, e.g. times/ages of fossil occurrences or their stratigraphic position, or a
pre_paleoTSobject.- pres_potential
function. Takes taphonomic conditions as input and returns the preservation potential (a number between 0 and 1). Must be vectorized, meaning if given a vector, it must return a vector of equal length.
- ctc
function, change in taphonomic conditions (ctc) with time or stratigraphic position. . Must be vectorized, meaning if given a vector, it must return a vector of equal length.
Value
if given event type data, a numeric vector, location/timing of events (e.g. fossil occurrences) after the taphonomic filter is applied. If given a pre_paleoTS object, returns another pre_paleoTS object with reduced number of specimens.
