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

Usage

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

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

# S3 method for 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)
#> Loading required package: Formula
#> Loading required package: plotmo
#> Loading required package: plotrix
#> Loading required package: TeachingDemos
#> 
#> Attaching package: ‘TeachingDemos’
#> The following object is masked from ‘package:klaR’:
#> 
#>     triplot

out <- butcher(earth_fit, verbose = TRUE)
#>  The butchered object is 2.02 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.
