stanfit-method-plot.RdThe default plot shows posterior uncertainty intervals and point
estimates for parameters and generated quantities. The plot method can
also be used to call the other rstan plotting functions via the
plotfun argument (see Examples).
# S4 method for stanfit,missing
plot(x, ..., plotfun)An instance of class stanfit.
A character string naming the plotting function to apply to the
stanfit object. If plotfun is missing, the default is to call
stan_plot, which generates a plot of credible intervals and
point estimates. See rstan-plotting-functions for the names and
descriptions of the other plotting functions. plotfun can be either the
full name of the plotting function (e.g. "stan_hist") or can be
abbreviated to the part of the name following the underscore
(e.g. "hist").
Optional arguments to plotfun.
A ggplot object that can be further customized
using the ggplot2 package.
Because the rstan plotting functions use ggplot2 (and thus the
resulting plots behave like ggplot objects), when calling a plotting
function within a loop or when assigning a plot to a name
(e.g., graph <- plot(fit, plotfun = "rhat")),
if you also want the side effect of the plot being displayed you
must explicity print it (e.g., (graph <- plot(fit, plotfun = "rhat")),
print(graph <- plot(fit, plotfun = "rhat"))).
if (FALSE) {
library(rstan)
fit <- stan_demo("eight_schools")
plot(fit)
plot(fit, show_density = TRUE, ci_level = 0.5, fill_color = "purple")
plot(fit, plotfun = "hist", pars = "theta", include = FALSE)
plot(fit, plotfun = "trace", pars = c("mu", "tau"), inc_warmup = TRUE)
plot(fit, plotfun = "rhat") + ggtitle("Example of adding title to plot")
