R package to import eye tracking recording generated by SR Research Eyelink eye tracker from EDF-files. It includes options to import events and/or recorded samples and extract individual events such as saccades, fixatoins, blinks, and recorded variables.

I somehow have discovered a new failure mode, wherein all the basic functions install, except for plot, such that invoking plot, e.g. with ``` eyelinkReader::plot ``, yields:
Error: 'plot' is not an exported object from 'namespace:eyelinkReader'
One can see the other functions that are installed, e.g. with lsf.str("package:eyelinkReader"):
adjust_message_time : function (object, prefix)
check_consistency_flag : function (consistency)
check_logical_flag : function (logical_flag)
check_string_parameter : function (string_parameter)
check_that_compiled : function (fail_loudly = TRUE)
compiled_library_status : function ()
compute_cyclopean_samples : function (object, fun = mean)
convert_header_codes : function (trial_headers)
convert_NAs : function (original_frame)
convert_recording_codes : function (trial_recordings)
extract_AOIs : function (object)
extract_blinks : function (object)
extract_display_coords : function (object, message_prefix = "DISPLAY_COORDS", silent = FALSE)
extract_fixations : function (object)
extract_saccades : function (object)
extract_triggers : function (object, message_prefix = "TRIGGER")
extract_variables : function (object)
logical_index_for_sample_attributes : function (import_samples, sample_attributes)
read_edf : function (file, consistency = "check consistency and report", import_events = TRUE,
import_recordings = TRUE, import_samples = FALSE, sample_attributes = NULL,
start_marker = "TRIALID", end_marker = "TRIAL_RESULT", import_saccades = TRUE,
import_blinks = TRUE, import_fixations = TRUE, import_variables = TRUE,
verbose = TRUE, fail_loudly = TRUE)
read_edf_file : function (filename, consistency, import_events, import_recordings,
import_samples, sample_attr_flag, start_marker_string, end_marker_string,
verbose)
read_preamble : function (file, fail_loudly = TRUE)
read_preamble_str : function (filename)
I've tried uninstalling R, and RStudio, and re-installing Can't figure out why this doesn't work anymore even though I had it working before (with my fork that fixes the path problem on Mac). Any ideas?
While the normal installation procedure worked a year or two ago on Macs, something broke it, perhaps an OS upgrade or Apple Silicon change.
Now when I try installation on multiple Macs here, which give the following error during the attempt to use edfapi during installation:
"tried: '/Library/Frameworks/edfapi.framework/edfapi.framework/Versions/A/edfapi' (no such file)"
Please note the redundant "edfapi.framework/edfapi.framework/". If one of those were deleted, it would find the file.
I worked out a fix for this. The zzz.R file that sets up the paths has this , specifically for Darwin, on line 70 :
library_path <-'/Library/Frameworks/edfapi.framework/'
Somewhere else that I haven't worked out, another edfapi.framework gets appended to that library_path.
If one simply deletes that edfapi.framework\ from line 70, everything works (except I get a really weird error where it says .rdb is corrupt in RStudio, whereas everything works in R.app, until I uninstall R and re-install it).
I'll do a bit more testing to ensure this works on our other Mac and then perhaps I should make the edit and set it as a pull request? Ideally to maintain possible backward compatibility, we would just add the version without edfapi.framework\ as a second directory that it also tries, but unfortunately I don't understand the system well enough to do that.
