Arguments

object	a `brmsfit` object
term	character; the smooth term for which the derivative is required.
n	numeric; the number of points to evaluate the derivative at.
eps	numeric; the finite difference.
prob	numeric; the density of the posterior summary.
prob_outer	numeric; the outer density of the posterior summary.
order	integer; the order of the derivative. Only first (`1`) and second (`2`) are supported.
deriv_posterior	return the posterior samples for the derivative as part of the object?

a curvish object containing summaries of the posterior derivative, posterior smooths.
