In ModelOriented/xai2shiny: Creates Shiny Application From A DALEX Explainer

Description

This function creates a Shiny application for explainers which are adapters for models created using the DALEX package. The application contains model performance and explanations to fully explore the model.

Usage

xai2shiny(
  ...,
  directory = NULL,
  selected_variables = NULL,
  run = TRUE,
  override = FALSE,
  verbose = TRUE
)

Arguments

...	one or more explainers created with DALEX::explain() function. They can be switched in top right corner of the application.
directory	path to the directory the application files will be created in. If NULL the application will be created in a temporary directory.
selected_variables	choosen variables for application start-up. There can be more added in the application interface through an input.
run	whether to run the Shiny application instantly
override	how to respond to a directory overriding case
verbose	whether to log in console internal function's steps

Examples

# Create models
library("ranger")
library("DALEX")
model_rf <- ranger(survived ~ .,
                   data = titanic_imputed,
                   classification = TRUE,
                   probability = TRUE)
model_glm <- glm(survived ~ .,
                 data = titanic_imputed,
                 family = "binomial")

# Create DALEX explainers
explainer_rf <- explain(model_rf,
                     data = titanic_imputed[,-8],
                     y = titanic_imputed$survived)

explainer_glm <- explain(model_glm,
                     data = titanic_imputed[,-8],
                     y = titanic_imputed$survived)

# Create and run the application

## Not run: 
xai2shiny(explainer_rf, explainer_glm)

## End(Not run)
