An R package for importing plain-text ASC data files from EyeLink eye
trackers into (relatively) well-structured data frames. EDF files first
must be converted to ASC using the edf2asc tool before they
can be imported.
Great efforts have been made to make this package fast, stable, and highly compatible. If you encounter any problems using eyelinker (or would like to make a feature request), please open an issue on the project’s GitHub page.
NOTE: As of version 0.2.0, eyelinker has been
rewritten almost entirely for greater stability and speed. Please refer
to the NEWS file for a comprehensive list of changes and
improvements.
