brms (version 1.3.1)

marginal_smooths.brmsfit: Display Smooth Terms

Description

Display smooth s and t2 terms of models fitted with brms.

Usage

"marginal_smooths"(x, smooths = NULL, probs = c(0.025, 0.975), resolution = 100, ...)
marginal_smooths(x, ...)

Arguments

x

An object usually of class brmsfit.

smooths

Optional character vector of smooth terms to display. If NULL (the default) all smooth terms are shown.

probs

The quantiles to be used in the computation of credible intervals (defaults to 2.5 and 97.5 percent quantiles)

resolution

Number of support points used to generate the plots. Higher resolution leads to smoother plots. Defaults to 100. If contour is TRUE, this implies 10000 support points for interaction terms, so it might be necessary to reduce resolution when only few RAM is available.

...

Currently ignored.

Value

For the brmsfit method, an object of class brmsMarginalEffects. See marginal_effects for more details and documentation of the related plotting function.

Details

Two-dimensional smooth terms will be visualized using contour plots.

Examples

## Not run: 
# set.seed(0) 
# dat <- mgcv::gamSim(1, n = 200,scale = 2)
# fit <- brm(y ~ s(x0) + s(x1) + s(x2) + s(x3), data = dat)
# # show all smooth terms
# plot(marginal_smooths(fit), rug = TRUE, ask = FALSE)
# # show only the smooth term s(x2)
# plot(marginal_smooths(fit, smooths = "s(x2)"), ask = FALSE)
# 
# # fit and plot a two-dimensional smooth term
# fit2 <- brm(y ~ t2(x0, x2), data = dat)
# marginal_smooths(fit2)
# ## End(Not run)
