New R package for Eyelink eye-trackers

Eyelink eye-trackers output an avalanche of disorganised crap. I’ve written an R package that will hopefully filter that crap for you. It’s called eyelinker and it’s on Github.

It outputs a set of dataframes containing raw traces, saccades, fixations and blinks, meaning it’s easy to produce plots like this one:


There’s a vignette explaining everything, just hit vignette(“basics”,package=”eyelinker”).

I’ve tested it on some of our local datasets but given the relatively free-form nature of Eyelink asc files, there’s no guarantee it will work everywhere.

Bug reports are welcome on the github issues page.
