The plot() method for the bayestestR::rope().

Usage

# S3 method for class 'see_rope'
plot(
  x,
  data = NULL,
  rope_alpha = 0.5,
  rope_color = "cadetblue",
  show_intercept = FALSE,
  n_columns = 1,
  ...
)

Arguments

x

An object.

data

The original data used to create this object. Can be a statistical model.

rope_alpha

Numeric specifying transparency level of ROPE ribbon.

rope_color

Character specifying color of ROPE ribbon.

show_intercept

Logical, if TRUE, the intercept-parameter is included in the plot. By default, it is hidden because in many cases the intercept-parameter has a posterior distribution on a very different location, so density curves of posterior distributions for other parameters are hardly visible.

n_columns

For models with multiple components (like fixed and random, count and zero-inflated), defines the number of columns for the panel-layout. If NULL, a single, integrated plot is shown.

...

Arguments passed to or from other methods.

Value

A ggplot2-object.

Examples

library(rstanarm)
library(bayestestR)
set.seed(123)
m <<- suppressWarnings(stan_glm(Sepal.Length ~ Petal.Width * Species, data = iris, refresh = 0))
result <- rope(m)
#> Possible multicollinearity between Petal.Width:Speciesversicolor and
#>   Petal.Width (r = 0.87), Petal.Width:Speciesvirginica and
#>   Petal.Width:Speciesversicolor (r = 0.79). This might lead to
#>   inappropriate results. See 'Details' in '?rope'.
