Helper function to generate interpolation values

Description

Helper function to generate interpolation values

Usage

interpolation_values(simulation_period = 140, transition_to_lgm = 13,
                     stable_lgm = 25, lgm_to_current = 7,
                     stable_current = 25, scenario_span = 3)

Arguments

simulation_period	(numeric) time in thousands of years for the complete period of simulation.
transition_to_lgm	(numeric) time in thousands of years for the transition period from current-like (interglacial) to glacial (LGM) climatic conditions.
stable_lgm	(numeric) time in thousands of years for the period when glacial (LGM) conditions are assumed to be relatively stable.
lgm_to_current	(numeric) time in thousands of years for the transition period from glacial (LGM) to current-like (interglacial) climatic conditions.
stable_current	(numeric) time in thousands of years for the period when current-like (interglacial) conditions are assumed to be relatively stable.
scenario_span	(numeric) time in thousands of years that have to pass for changing the scenario. Default = 3 (three thousand years).

Value

A list containing:

• a vector with proportions of interglacial conditions corresponding to each interpolation

• a vector represenitng the position of each interpolation in the previous vector.
