FossilSim (version 2.4.1)

sim.gradient: Simulate an environmental gradient

Description

Function returns a vector using the sine wave function $y=depth\ast sin(cycles\ast pi\ast (x-1/4))$ for a given set of intervals. This vector can be used as a gradient to simulate fossils under an environment-dependent model of fossil recovery using the function sim.fossils.environment.

Usage

sim.gradient(strata, depth = 2, cycles = 2)

Value

vector of sampled water depths.

Arguments

strata

Number of stratigraphic intervals.

depth

Maximum water depth.

cycles

Number of cycles (e.g. transgressions and regressions).

Examples

strata = 100
wd = sim.gradient(strata)
plot(wd, type="l")
