Manipulating and Joining Data in R with dplyr

Description

Prerequisite: Introduction to R for Absolute Beginners or some experience using R. 

The dplyr package is a popular R package that people often use to manipulate and join data sets. You will need to have either some basic knowledge about using R or have previously attended the Introduction to R for Absolute Beginners workshop in order to take this one.

Join Johns Hopkins Data Services for this workshop to learn to use several functions—including mutate(), filter(), select(), summarize(), and group_by()—in dplyr to manipulate data for the first half of the workshop. For the second part of this workshop, you will learn the join functions—left_join(), right_join(), inner_join(), semi_join(), anti_join(), full_join(), bind_rows() and bind_cols()—and set operations—union(), intersect() and setdiff()—in dplyr to combine two data sets. You will have plenty of opportunities to do hands-on activities on your laptop and work on data sets provided by instructors.
