tree: Interfaces for tree package for data science pipelines.

ntbt_tree(data, ...)

Arguments

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

Object returned by interfaced function.

Examples

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

data(cpus, package="MASS")

## Original function to interface
cpus.ltr <- tree(log10(perf) ~ syct+mmin+mmax+cach+chmin+chmax, cpus)
cpus.ltr
summary(cpus.ltr)
plot(cpus.ltr)
text(cpus.ltr)

## The interface reverses the order of data and formula
cpus.ltr <- ntbt_tree(cpus, log10(perf) ~ syct+mmin+mmax+cach+chmin+chmax)
cpus.ltr
summary(cpus.ltr)
plot(cpus.ltr);  text(cpus.ltr)

## so it can be used easily in a pipeline.
cpus %>%
  ntbt_tree(log10(perf) ~ syct + mmin + mmax + cach + chmin + chmax) %>%
  summary()

cpus %>%
  ntbt_tree(log10(perf) ~ syct + mmin + mmax + cach + chmin + chmax) %T>%
  plot() %>%
  text()

iris %>%
  ntbt_tree(Species ~.) %>%
  summary()

## End(Not run)
