Event Details

Managing Data with R

 Before you can analyze data, it must be in the right form. Getting it into that form is often where we spend most of our time. This 4-hour workshop shows how to perform the most commonly used data management tasks in R. We will cover how to use R’s popular add-on packages (dplyr, stringr, lubridate, tidyr, broom, compare, TableToLongForm, sqldf) and compare them to R’s older built-in functions.

Most of our time will be spent working through examples that you may run simultaneously on your computer. However, the handouts include each step and its output, so feel free to just relax and take notes. Most examples come from the extensive data management examples in the books, R for SAS and SPSS Users, R for Stata Users, and the web site, http://r4stats.com. That makes it easy to review what we did later with full explanations, or to learn more about a particular subject by extending an example which you have already learned.

At the end of the workshop, you will receive a set of practice exercises for you to do on your own time, as well as solutions to the problems. The instructor is available via email to address these problems or any other topics in his workshops or books.

Prerequisites

Attendees should know basic R programming, including how to read data files and call functions.

 Learning Outcomes

 When finished, you will be able to prepare most data sets for analysis.
