axe-mda: Axing a mda.

In butcher: Model Butcher

Axing a mda.

Description

mda and fda objects are created from the mda package, leveraged to carry out mixture discriminant analysis and flexible discriminat analysis, respectively.

Usage

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

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

## S3 method for class 'mda'
axe_env(x, verbose = FALSE, ...)

## S3 method for class 'fda'
axe_env(x, verbose = FALSE, ...)

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

## S3 method for class 'fda'
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 mda object.

Examples

library(mda)

mtcars$cyl <- as.factor(mtcars$cyl)

fit <- mda(cyl ~ ., data = mtcars)
out <- butcher(fit, verbose = TRUE)

fit2 <- fda(cyl ~ ., data = mtcars)
out2 <- butcher(fit2, verbose = TRUE)

# Another mda object
data(glass)
wrapped_mda <- function(fit_fn) {
  some_junk_in_environment <- runif(1e6)
  fit <- fit_fn(Type ~ ., data = glass)
  return(fit)
}

lobstr::obj_size(wrapped_mda(mda))
lobstr::obj_size(butcher(wrapped_mda(mda)))

lobstr::obj_size(wrapped_mda(fda))
lobstr::obj_size(butcher(wrapped_mda(fda)))
