*** This package is in very early development. Feedback is encouraged!!! ***

Installation

Install the development version from Github with:

## install devtools if not already
if (!requireNamespace("devtools", quietly = TRUE)) {
  install.packages("devtools")
}
## install tidymlm from Github
devtools::install_github("mkearney/tidymlm")

Load the package (it, of course, plays nicely with tidyverse).

## load tidyverse
library(tidyverse)

## load tidymlm
library(tidymlm)
