Data Wrangling in R
Data is often messy, requiring cleaning and restructuring before it can be reliably used in a program or project. In this course, learners will augment their understanding of base R using an open-source set of packages intended for data cleaning and wrangling, the tidyverse. After installing this package, learners will practice working with functions that allow data to be selected, filtered, summarized, rearranged, and otherwise transformed according to analyst-vetted best practices.
