Advanced Methods for Processing and Analyzing Eye-Tracking Data Using R

The software R can provide powerful and flexible tools for researchers to process and analyze data. This chapter introduces (1) using R to import and manage eye-tracking data and export results; (2) the apply family, which increases the efficiency of eye-tracking data extraction and manipulation; (3) statistical methods, such as correlation and regression; and (4) processing scanpath data and applying the R package GrpString to discover common patterns in a scanpath group. By using data from a previous science education study, the examples through this chapter illustrate how all of these tasks can be seamlessly accomplished in the R environment.
