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 datasets. 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 and you will 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 (e.g.,?left_join(),?right_join(),?inner_join(),?semi_join(),?anti_join(),?full_join(),?bind_rows() and?bind_cols()) and set operations (e.g.,?union(),?intersect() and?setdiff()) in?dplyr?to combine two datasets.

You will have plenty of opportunities to do hands-on activities on your laptop and work on datasets provided by instructors.?
