The ultimate goal of data pre-processing journey is to end up with a clean and organized analytical dataset, ready to be used for further analysis and insights. This tutorial aims to help you enhance your data preparation skills as a data scientist or data analyst using the R statistical programming language.

We will explore a more efficient method of working with multiple files or data objects using functional programming tools provided by the purrr package. This approach allows us to accomplish more tasks with concise and efficient code.
