plot.brmsfit: Trace and Density Plots for MCMC Samples

Description

Trace and Density Plots for MCMC Samples

Usage

"plot"(x, pars = NA, parameters = NA, combo = c("dens", "trace"), N = 5, exact_match = FALSE, theme = NULL, plot = TRUE, ask = 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 group-level and smooth effects are plotted.
parameters
A deprecated alias of pars
combo
A character vector with at least two elements. Each element of combo corresponds to a column in the resulting graphic and should be the name of one of the available link[bayesplot:MCMC-overview]{MCMC} functions (omitting the mcmc_ prefix).
N
The number of parameters plotted per page.
exact_match
Indicates whether parameter names should be matched exactly or treated as regular expression. Default is FALSE.
theme
A theme object modifying the appearance of the plots. For some basic themes see ggtheme and theme_default. Can be defined globally for the current session, via theme_set.
plot
logical; indicates if plots should be plotted directly in the active graphic device. Defaults to TRUE.
ask
logical; indicates if the user is prompted before a new page is plotted. Only used if plot is TRUE.
newpage
logical; indicates if the first set of plots should be plotted to a new page. Only used if plot is TRUE.
...
Further arguments passed to mcmc_combo.

Value

An invisible list of gtable objects.

Examples

Run this code
## Not run:  
# 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_") 
# ## End(Not run)
