Event Details

Managing Data with R

Before you can analyze data, it must be in a form you can analyze. That is where we typically spend most of our time. This 4-hour workshop shows how to perform the most commonly used data management tasks in R. For many topics we will cover both the standard built-in approach and then perform the same task using add-on packages that are often much easier to use.

We will devote most of our time to working through examples that you may run simultaneously on your computer. However, handouts will include each step and its output if you prefer instead just relax and take notes. Most examples come from the extensive data management examples in R for SAS and SPSS Users, R for Stata Users, and 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. (No coverage of SAS, SPSS or Stata is included in this workshop.)

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 will be available via email to address these problems or any other topic in the workshop.

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.

Presenter

Robert A. Muenchen is the creator of the web site http://r4stats.com and is the author of the books, R for SAS and SPSS Users, and, with Joseph Hilbe, R for Stata Users.
