Axing an earth object.

earth objects are created from the earth package, which is leveraged to do multivariate adaptive regression splines.

Usage

# S3 method for class 'earth'
axe_call(x, verbose = FALSE, ...)

# S3 method for class 'earth'
axe_data(x, verbose = FALSE, ...)

# S3 method for class 'earth'
axe_fitted(x, verbose = FALSE, ...)

Arguments

x

A model object.

verbose

Print information each time an axe method is executed. Notes how much memory is released and what functions are disabled. Default is FALSE.

...

Any additional arguments related to axing.

Value

Axed earth object.

Examples

# Load libraries
library(parsnip)

# Create model and fit
earth_fit <- mars(mode = "regression") %>%
  set_engine("earth") %>%
  fit(Volume ~ ., data = trees)

out <- butcher(earth_fit, verbose = TRUE)
#> ✖ The butchered object is 2.03 kB larger than the original. Do not butcher.

# Another earth model object
suppressWarnings(suppressMessages(library(earth)))
earth_mod <- earth(Volume ~ ., data = trees)
out <- butcher(earth_mod, verbose = TRUE)
#> ✖ The butchered object is 712 B larger than the original. Do not butcher.
