Hi - sorry for the late reply. Which model are you using? Do you have a handbook for it? Apparently the file format has changed a bit from the manual I have for the Eyelink 1000. In the meantime, try disabling the "input" field in the samples data when generating the asc files.
Actually, better yet: use the current github version:
devtools::install_github('dahtah/eyelinker')
Hi,
I had the same error and tried both solutions - now I get a different error: "Warning: 169041 parsing failures." (I am using an Eyelink 1000 and your package used to work perfectly for me - maybe a recent update?)
Thanks in advance!
Hi @scienceanna and @NaomiHavron, in the off-chance you're still looking for a solution to this problem, the issue was that your ASC files contained input port data in the samples (the 127.0 column) which eyelinker 0.1 didn't support. The latest CRAN release of eyelinker (0.2.0) fixes the issue, importing your example files just fine:
library(eyelinker)
a <- read.asc('test.asc')
a$raw
## # A tibble: 7,459 x 7

Hi - thanks for the package, it's very helpful!
I'm encountering a problem with the read.asc function for some data I'm working on - see the attached files. test_asc_files.zip
test.asc is a sample of 2 trials from an experiment. When attempting to run this with read.asc, I get the following error:
Error in vector(type, length) : vector: cannot make a vector of mode 'NULL'.
test_2.asc is a reduced snippet of the data that just has 1 trial - and this runs fine with read.asc for me.
Let me know if you need any more info - and thanks so much for any help you can give.
