ntbt_regsubsets(data, ...)

Arguments

data	data frame, tibble, list, ...
...	Other arguments passed to the corresponding interfaced function.

Examples

## Not run: 
library(intubate)
library(magrittr)
library(leaps)

## Original function to interface
fit <- regsubsets(Fertility ~ ., data = swiss, nbest = 2)
summary(fit)

## The interface reverses the order of data and formula
fit <- ntbt_regsubsets(data = swiss, Fertility ~ ., nbest = 2)
summary(fit)

## so it can be used easily in a pipeline.
swiss %>%
  ntbt_regsubsets(Fertility ~ ., nbest = 2) %>%
  summary()

## End(Not run)
