mousetrap R package with E-Prime data?
Hello, I am a PhD student and am conducting my first mouse-tracking experiment. I am collecting data online with E-Prime, since mouse-tracking is not supported on OSWeb.
I was wondering if there is any way I can prepare my data to run analyses with the mousetrap R package?
I have seen that the mt_import_mousetrap() function's output is an array of "trajectories" linked to a df containing the rest of the data. Is there a way I can accomplish that by hand from my data? Would it work afterwards, or are there further considerations I am not aware of?
Here an example of how my data look right now:
Alternatively, are there any other packages that someone would recommend?
Thank you in advance for your help!

Hi Carlotta,
the mousetrap R package offers different import functions depending on the format of the mouse-tracking data, so you should also be able to import your data and analyse it with mousetrap.
Specifically, you first would have to read your data into R - I don't know how the EPrime files look like but I hope that there is an easy way to get them into R.
The result of this will likely be a data.frame. This can then be imported into mousetrap. From your screenshot, I would guess that the mt_import_long function should work for your case (see documentation here: http://pascalkieslich.github.io/mousetrap/reference/mt_import_long.html).
The command would likely look something like this:
mt_data <- mt_import_long(raw_data, xpos_label = "x", ypos_label = "y", timestamps_label = "t", mt_id_label = c("Subj", "Trial"), mt_seq_label = "step")Hope this helps!
Best

Thank you so much Pascal, this worked beautifully!
