Tools for Creating Tuning Parameter Values

Many models contain tuning parameters (i.e. parameters that cannot be directly estimated from the data). These tools can be used to define objects for creating, simulating, or validating values for such parameters.

Build Status Coverage status CRAN\_Status\_Badge Downloads

This package contains tools to create and manage values of tuning parameters and is designed to integrate well with the parsnip package.

The name reflects the idea that tuning predictive models can be like turning a set of dials on a complex machine under duress.

To install:

install.packages("dials")

## for development version:
require("devtools")
install_github("tidymodels/dials")
