Error in 'Set scale'

[Gotargis]

Hello @sjmgarnier,

I am in the final step before tracking, but when I click on "Set scale," both the display and control windows close, and I get this message in R:

Warning: Error in click: unused argument ("trackR")
84: rbind
83: rbind
82: observe [/Library/Frameworks/R.framework/Versions/4.5-arm64/Resources/library/trackR/modules/trackR/trackServer.R#90]
81: observer:observeEvent(input$scale_x)
2: shiny::runApp
1: trackR

Do you know how I can fix it?

Thanks in advance.

@Gotargis Hmm, I've never encountered this issue before. I will need to do a bit of digging, though I’m not sure when I'll have time. I have put the development of trackR on hold to focus on trackRai instead (https://swarm-lab.github.io/trackRai/), so my time is a bit limited at the moment. I'll see if I can find time over the weekend. Can you describe the steps that got you there? That might help me reproduce the bug on my machine.

@sjmgarnier sure, no problem! I am running the trackR on macbook pro M4, R studio (version 2025.05.0). I uploaded the video 'test.mp4', the settings, background image and R script I am using in this folder: (https://drive.google.com/drive/folders/1L2fxf8PpfD3WP4CSkfn2HSJHnUZHhQwF?usp=drive_link)

Please, let me know if you need more information. I appreciate your effort in helping me.

@Gotargis I know it's been a while, but I have been working on a complete overhaul of trackR, so much so that I created a new package for it. You can give it a try here: https://swarm-lab.github.io/trackRcv/. It should resolve your issue, but also provide a better user experience in general. The installation process is also much simpler now: https://swarm-lab.github.io/trackRcv/articles/z1_installing_trackRcv.html. I'm still in the process of writing the documentation, and there are a few things that haven't been fully ported over yet, but I think it should be good enough for your use case.

@sjmgarnier It worked! I tested with a trial; looks good. I'll apply it to the full dataset tomorrow. If it works, I will make sure to cite your software properly in my paper. Thank you!

@Gotargis I'm glad to hear that. If you run into any issues, or if there is something that doesn't work as expected, please don't hesitate to reach out again.
