Closure for simulating logistic curve

Source: R/sim_survey.R

This closure is useful for simulating catchability (q) inside the sim_survey() function.

sim_logistic(k = 2, x0 = 3, plot = FALSE)

Arguments

k

Steepness of the curve.

x0

The x-value at the midpoint of the sigmoid.

plot

Logical. Should the relationship be plotted?

Value

A function that can be passed to sim_survey().

Examples

logistic_fun <- sim_logistic(k = 2, x0 = 3, plot = TRUE)
logistic_fun(x = 1:10)
