R butcher axe-ipred 砍倒一棵装袋的树。

*_bagg对象是从创建的伊普雷德包，用于装袋分类、回归和生存树。

用法

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

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

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

# S3 method for regbagg
axe_ctrl(x, verbose = FALSE, ...)

# S3 method for classbagg
axe_ctrl(x, verbose = FALSE, ...)

# S3 method for survbagg
axe_ctrl(x, verbose = FALSE, ...)

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

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

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

# S3 method for regbagg
axe_env(x, verbose = FALSE, ...)

# S3 method for classbagg
axe_env(x, verbose = FALSE, ...)

# S3 method for survbagg
axe_env(x, verbose = FALSE, ...)

参数

x: 一个模型对象。
verbose: 每次执行 ax 方法时打印信息。记录释放了多少内存以及禁用了哪些函数。默认为 FALSE 。
...: 与砍伐相关的任何其他参数。

值

删除*_bagg 对象。

例子

library(ipred)

fit_mod <- function() {
  boop <- runif(1e6)
  bagging(y ~ x, data.frame(y = rnorm(1e4), x = rnorm(1e4)))
}

mod_fit <- fit_mod()
mod_res <- butcher(mod_fit)

weigh(mod_fit)
