This is a small package that offers a set of customizable higher-order recipe
step functions compatible with the [`recipes`](https://CRAN.R-project.org/package=recipes) package. 

## Installation

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

```{r, eval = FALSE}
devtools::install_github("smaakage85/customsteps")
```

## Customizable higher-order step functions

Let me just remind you of the definition of [**higher-order functions**](https://en.wikipedia.org/wiki/Higher-order_function):

> *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.
