Description

Trace and Density Plots for MCMC Samples

Usage

## S3 method for class 'brmsfit':
plot(x, pars = NA, parameters = NA, N = 5,
  theme = ggplot2::theme(), ask = TRUE, do_plot = TRUE, newpage = TRUE,
  ...)

Arguments

x

An object of class brmsfit.

pars

Names of the parameters to plot, as given by a character vector or a regular expression. By default, all parameters except for random effects are plotted.

parameters

A deprecated alias of pars

N

The number of parameters plotted per page.

theme

A theme object modifying the appearance of the plots. For some basic themes see ggtheme. Can be defined globally for the curr

ask

logical; indicates if the user is prompted before a new page is plotted. Only used if do_plot is TRUE.

newpage

logical; indicates if the first set of plots should be plotted to a new page. Only used if do_plot is TRUE.

Further arguments passed to arrangeGrob.

Value

• A (possibly invisible) list of gtable objects.

Examples

fit <- brm(count ~ log_Age_c + log_Base4_c * Trt_c 
           + (1|patient) + (1|visit), 
           data = epilepsy, family = "poisson")
## plot fixed effects as well as standard devations of the random effects
plot(fit)
## plot fixed effects only
plot(fit, pars = "^b_")
