This chapter demonstrates the features of pipeline(). This function evaluates both argument-based and expression-based pipelines. What makes it special is that it does not require using pipe operator %>>%, nor does it create a Pipe object as a wrapper. Using pipeline(), you will be able to write cleaner pipeline expressions with less noise.
In other words, pipeline() implements two similar operator-free mechanisms for building a pipeline. The good thing is that you don't have to sacrifice any feature to use it, that is, all features of %>>% are supported in pipeline() and some are even made easier to use.
