Using dplyr's slice and arrange functions in R to order and pick rows from a data frame (CC162)

November 11, 2021 • PD Schloss • 1 min read • •

In this episode of Code Club, Pat uses dplyr’s slice and arrange functions to show how you can order and grab rows out of a data frame using R. He’ll cover how to do an ascending and descending sort using arrange and desc and the slice_head, slice_tail, slice_max, slice_min, and slice_sample functions to grab rows with particular characteristics. We’ll also talk about top_n. He’ll demonstrate how to use these functions with a massive data frame that we downloaded from Our World in Data that describes COVID-19 vaccination rates by country and day.
