This is a small package that offers a set of customizable higher-order recipe step functions compatible with the recipes package.

customsteps can be installed from CRAN with install.packages('customsteps'). If you want the development version then install directly from GitHub:

devtools::install_github("smaakage85/customsteps")

Let me just remind you of the definition of higher-order functions:

In mathematics and computer science, a higher-order function is a function that does at least one of the following: 1. takes one or more functions as arguments, 2. returns a function as its result.

customsteps offers higher-order recipe step functions, that create specifications of recipe steps, that will transform or filter the data in accordance with (custom) input functions.

For more details on how to use customsteps please take a look at the package vignette.
