Any learning algorithm is only as good as its input data, and in many cases, the input data is complex, messy, and spread across multiple sources and formats. Due to this complexity, often the largest portion of effort invested in machine learning projects is spent on data preparation and exploration.

This chapter approaches data preparation in three ways. The first section discusses the basic data structures R uses to store data.
