eyelinker's Issues

eyelinker detects saccades/fixations/ etc., but does not return $raw tibble

Hi Austin,

I'm using eyelinker version 0.2.0. (reinstalled today) to read data from an Eyelink 1000 (https://tsgdoc.socsci.ru.nl/index.php?title=Eyetrackers#EyeLink_1000).

If I use read.asc to read my raw data, I get the following warning:

In process_raw(inp[is_raw], block[is_raw], info) :
  Unknown columns in raw data. Assuming first one is time, please check the others

What happens is that the sacc, fix, blinks, msg, and info tibble all look fine (I don't use input or button), but the raw tibble is empty:

> dat$raw
# A tibble: 1 x 8

Any idea how this happens and how to fix it? Thanks already for any pointers!

I used your package about a year ago (May 2019) on data from the same eye-tracker, and everything worked fine---has there been any major update in the package? Unfortunately I can't find back the version I used back then.

Below the first rows of the raw data file:

Problem with function read.asc

Hi there, I am experiencing a weird issue with the read.asc function. It has been working a couple of days ago and then suddenly stopped to do so.

I use the following function to open my eyertracking data that I converted into an ASC file:

`> test_dat <- read.asc("example_file.asc")'

And I keep receiving this error:

Error in read.asc("example_file.asc") : could not find function "read.asc"

I am using R Studio 2023.06.1+524 and am running it on a Macbook with M1 chip with macOS Monterey (12.1).

I would be very thankful for any recommendations about what the issue could be. Thanks a lot in advance!
