Error in colorSelectorDrop.ekb: object 'squareButton' not found

[ndrshfflr]

I am using R Version 4.4.1 (2024-06-14) -- "Race for Your Life") and RStudio Version 2024.04.2+764 (2024.04.2+764) to run gmShiny v0.1.4 and getting an error when running the code. The full output is below:

Furthermore, I had lots of issues with installing packages with the code listed on the website. To make all packages work, I had to use install.packages() in order for them to work.

Hi there,

It appears that updating the package 'shiny' to v1.9.1, along with a few other updated packages, fixed this error on my device (same R and RStudio versions as yours). See below for all packages and versions. It may be that not all these package updates are necessary for gmShiny to work on R 4.4.1, but if the shiny update is not sufficient to fix the issue on your end, please install the listed packages and versions and try again.

It is worth noting that this update to the shiny package will result in some warnings in your R console when gmShiny is launched, but the app should still run smoothly. I am currently working to address these warnings (and they are simply aesthetic components of the app, not computational issues), but I wanted to share my functional fix that gives you access to the app. I will be working on a gmShiny patch that accommodates all the changes to the new shiny package.

As to your second comment, I will edit the website to update the needed package versions and address the issues with the install_version function. Thank you for bringing it to our attention, and please let us know if you find more issues.

Thank you so much for your help, @ebaken. Sadly, updating the packages did not resolve the issue.

Ok, could you send me more details on the required packages and their versions? As this might take a bit of back and forth, we can continue this trouble shooting via e-mail ***@***.***). Best, Erica

Hi Erica,

Unfortunately, I'm encountering the same issue.

Warning: Error in colorSelectorDrop.ekb: object 'squareButton' not found 107: colorSelectorDrop.ekb [support.functions.R#255] 1: shiny::runApp Warning: Error in colorSelectorDrop.ekb: object 'squareButton' not found 107: colorSelectorDrop.ekb [support.functions.R#255] 1: shiny::runApp

I have the following package versions installed:
shiny: 1.11.1
RRPP: 2.1.2
geomorph: 4.0.10
shinyMatrix: 0.8.0
shinyjqui: 0.4.1 (not shinyqui)
ape: 5.8-1
stringi: 1.8.7
RColorBrewer: 1.1-3
shinybusy: 0.3.3

Plus:
shinyjs 2.1.0
shinywidgets 0.9.0
shinydashboard 0.7.3
shinythemes 1.2.0
shinyalert 3.1.0
shinymeta 0.2.1
prettycode 1.1.0
stringr 1.5.1
reactlog 1.1.1
StereoMorph 1.6.7

I can see that squareButton is called in the support.functions.R script, but I can't find any information about it for shinyWidgets.

Thanks,
Felix

Hi Felix, I see that most of your shiny-related packages are newer versions than what I used to create the support.functions.R script. I suspect the problem here is that shinyWidgets version 0.9.0 doesn’t support the squareButton function I call on from v0.6.0. If you could, please re-install the older version of shinyWidgets and see if that fixes the problem. devtools::install_version("shinyWidgets", version = "0.6.0”) Best, Erica

Hi Erica,

Yes, that works. I installed 0.6.0 using the remotes package, and gmShiny now works.

I'll have to re-install 0.9.0 for other apps, but good to know this fix.

Thanks,
Felix
