ABSTRACT
This chapter introduces the R Commander graphical user interface (GUI) by demonstrating its use for a simple problem: constructing a contingency table to examine the relationship between two categorical variables. In developing the example, I explain how to start the R Commander, describe the structure of the R Commander interface, show how to read data into the R Commander, how to modify data to prepare them for analysis, how to draw a graph, how to compute numerical summaries of data, how to create a printed report of your work, how to edit and re-execute commands generated by the R Commander, and how to terminate your R and R Commander session-in short, the typical work flow of data analysis using the R Commander. I also explain how to customize the R Commander interface.
