Prepare objects for plotting or plot objects

data_plot() extracts and transforms an object for plotting, while plot() visualizes results of functions from different packages in easystats-project. See the documentation for your object's class:

• bayestestR::bayesfactor_models()

• bayestestR::bayesfactor_parameters()

• bayestestR::equivalence_test()

• bayestestR::estimate_density()

• bayestestR::hdi()

• bayestestR::p_direction()

• bayestestR::p_significance()

• bayestestR::si()

• effectsize::effectsize()

• modelbased::estimate_contrasts()

• parameters::compare_parameters()

• parameters::describe_distribution()

• parameters::model_parameters()

• parameters::principal_components()

• parameters::n_clusters()

• parameters::n_factors()

• parameters::simulate_parameters()

• performance::check_collinearity()

• performance::check_heteroscedasticity()

• performance::check_homogeneity()

• performance::check_normality()

• performance::check_outliers()

• performance::compare_performance()

• performance::performance_roc()

• performance::check_predictions()

Usage

data_plot(x, ...)

# S3 method for compare_performance
data_plot(x, data = NULL, ...)

Arguments

x

An object.

...

Arguments passed to or from other methods.

data

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

Details

data_plot() is in most situation not needed when the purpose is plotting, since most plot()-functions in see internally call data_plot() to prepare the data for plotting.

Many plot()-functions have a data-argument that is needed when the data or model for plotting can't be retrieved via data_plot(). In such cases, plot() gives an error and asks for providing data or models.

Most plot()-functions work out-of-the-box, i.e. you don't need to do much more than calling plot(<object>) (see 'Examples'). Some plot-functions allow to specify arguments to modify the transparency or color of geoms, these are shown in the 'Usage' section.

Examples

library(bayestestR)
library(rstanarm)

model <<- suppressWarnings(stan_glm(
  Sepal.Length ~ Petal.Width * Species,
  data = iris,
  chains = 2, iter = 200, refresh = 0
))

x <- rope(model, verbose = FALSE)
plot(x)


x <- hdi(model)
plot(x) + theme_modern()


x <- p_direction(model, verbose = FALSE)
plot(x)


model <<- suppressWarnings(stan_glm(
  mpg ~ wt + gear + cyl + disp,
  chains = 2,
  iter = 200,
  refresh = 0,
  data = mtcars
))
x <- equivalence_test(model, verbose = FALSE)
plot(x)
