sim.gradient | R Documentation |
Function returns a vector using the sine wave function y = depth*sin(cycles*pi*(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
.
sim.gradient(strata, depth = 2, cycles = 2)
strata |
Number of stratigraphic intervals. |
depth |
Maximum water depth. |
cycles |
Number of cycles (e.g. transgressions and regressions). |
vector of sampled water depths.

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