README.md
eyelinker
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.
