Simple deterministic smooth shapes for simulation truth — sim_smooth

These helpers are intended for readable simulation specifications. They work best with inputs already scaled to [0, 1], for example by sim_rescale01().

Usage

sim_smooth_linear(x, slope = 1, center = TRUE)

sim_smooth_sin(x, amplitude = 1, period = 1, phase = 0)

sim_smooth_bump(x, amplitude = 1, location = 0.5, width = 0.15)

sim_smooth_sigmoid(x, amplitude = 1, location = 0.5, steepness = 10)

sim_smooth_u(x, amplitude = 1, location = 0.5)

sim_smooth_wiggle(x, amplitude = 1)

Arguments

x: Numeric input, usually scaled to [0, 1].
slope: Linear slope.
center: Logical; if TRUE, center x around 0.5 for the linear shape.
amplitude: Effect amplitude.
period: Period of the sinusoid in units of x.
phase: Phase shift for the sinusoid.
location: Center/location of the bump, sigmoid, or U-shape.
width: Width of the Gaussian bump.
steepness: Steepness of the sigmoid transition.

Value

Numeric vector of the same length as x.
