Fit a apd_hat_values

Source: R/hat_values-fit.R

apd_hat_values() fits a model.

apd_hat_values(x, ...)

# S3 method for default
apd_hat_values(x, ...)

# S3 method for data.frame
apd_hat_values(x, ...)

# S3 method for matrix
apd_hat_values(x, ...)

# S3 method for formula
apd_hat_values(formula, data, ...)

# S3 method for recipe
apd_hat_values(x, data, ...)

Arguments

x

Depending on the context:

  • A data frame of predictors.

  • A matrix of predictors.

  • A recipe specifying a set of preprocessing steps created from recipes::recipe().

...

Not currently used, but required for extensibility.

formula

A formula specifying the predictor terms on the right-hand side. No outcome should be specified.

data

When a recipe or formula is used, data is specified as:

  • A data frame containing the predictors.

Value

A apd_hat_values object.

Examples

predictors <- mtcars[, -1]

# Data frame interface
mod <- apd_hat_values(predictors)

# Formula interface
mod2 <- apd_hat_values(mpg ~ ., mtcars)

# Recipes interface
library(recipes)
