plot method for class "hef".
# S3 method for hef
plot(x, y, ..., params = c("hyper", "ru", "pop"),
which_pop = NULL, plot_type = NULL, one_plot = FALSE,
add_legend = FALSE, legend_position = "topright",
legend_text = NULL, num = 100)
Arguments
| x |
an object of class "hef", a result of a call to
ru. |
| y |
Not used. |
| ... |
Additional arguments passed to plot.ru,
hist or pairs.
In particular, ru_scale = TRUE produces a plot using the
parameterization used for ratio-of-uniforms sampling. |
| params |
A character scalar that determines to which parameters the
plots relate.
"hyper": the posterior sample of all hyperparameter
values in \(\phi\) is plotted using plot.ru.
"ru": then only the posterior sample generated using
ru is plotted using plot.ru.
This produces a different plot to params = "hyper" if ru
is used only on a subset of \(\phi\). For example, this may be
the case if x is the result of a call to hanova1.
See vignette("bang-c-anova-vignette", package = "bang") for
information.
"pop": posterior samples and/or densities of the
population-specific parameter \(\theta\) are plotted. The
population(s) included are determined by which_pop and the
type of plot is determined by plot_type.
If plot_type is not supplied then it is set to "dens".
|
| which_pop |
An integer vector or character scalar.
If params = "pop" then which_pop indicates which
populations to include in the plot. If which_pop is supplied then
params is set to "pop". If which_pop = "all"
then all populations are included. If there are many populations then
this may fail if plot_type = "pairs" and/or
one_plot = FALSE. |
| plot_type |
A character scalar that determines the type of plot
produced when params = "pop". If plot_type is supplied
then params is set automatically to "pop".
"sim": histograms of the posterior samples
of \(\theta\) for the populations in which_pop.
"dens": estimates of the marginal posterior
densities of \(\theta\) for the populations in which_pop.
"both": both the histograms and estimated posterior densities.
"pairs": pairwise scatter plots of the posterior samples of
\(\theta\) for the populations in which_pop, which must have
length greater than one.
|
| one_plot, add_legend, legend_position, legend_text |
Only relevant if
plot_type = "dens". If one_plot = TRUE then the estimated
marginal posterior densities are plotted in the same graph and if
add_legend = TRUE then a legend is added to this plot using
legend in the position indicated by
the character scalar legend_position.
A character vector legend_text may be used to override the
default legend text. |
| num |
A numeric scalar. If plot_type == "dens" or
plot_type == "both" then num gives the number of
points at which the marginal densities are evaluated to produce plots. |
Examples
