bru() uses INLA::inla() to fit models. The latter estimates the posterior densities of all random effects in the model. This function serves to access and plot the posterior densities in a convenient way.

Requires the ggplot2 package.


# S3 method for bru
plot(x, ...)



a fitted bru() model.


A character naming the effect to plot, e.g. "Intercept". For random effects, adding index = ... plots the density for a single component of the latent model.
