discrete_gradient: construct discretized gradient

In StratPal: Stratigraphic Paleobiology Modeling Pipelines

construct discretized gradient

Description

Constructs a discretized gradient along time/height. The gradient value between bounds[i] and bounds[i+1] (not including) is vals[i], values above/below the largest/smallest value of bounds are assigned outval. Helper function for usage with discrete_niche

Usage

discrete_gradient(vals, bounds, outval = "")

Arguments

vals	vector, values of the gradient
bounds	vector of strictly increasing values, e.g. times or stratigraphic heights.
outval	value, gradient value assigned outside of values covered by bounds

Value

a functions assigning continuous values (e.g., times or heights) discrete niches
