VWPre
I develop and maintain VWPre, an R package for preprocessing and plotting Visual World Paradigm eye-tracking data. This work is in collaboration with Aki-Juhani Kyröläinen, Jacolien van Rij and Juhani Järvikivi. The current version of the package can be found on CRAN: VWPre
There are several elaborated vignettes designed to help users become comfortable with the functionality of the package.
