"R is not responding to your request" after using explor

[Chatoranga]

Hello, I use the explor function but R very often crashes when I close the explor window. R studio displays "R is not responding your request to interrupt processing so to stop the current operation you may need to terminate R entirely.", and I lose everything in the workspace. What can I do ?

[juba]

Well, it's a bit complicated to know where the problem can come from... What version of RStudio are you using ?

[gabrielparriaux]

Just to let you know that I have the same problem, using this RStudio: Version 2023.03.1+446 (2023.03.1+446) on a MacBook ARM64.

It does not always occur, but most of the time.

Refuse to interrupt the process in the prompt, hit escape key in the console and it gets back to normal.

[juba]

Do you have the same error message "R is not responding your request to interrupt processing so to stop the current operation you may need to terminate R entirely." ?

Do you know if it happens with different types of results (CA, MCA, speMCA...) or specifically with one kind ?

[gabrielparriaux]

Yes, it’s this message. Here is a screenshot:

I only tested it with CA and MCA. It happens with both, but not every time (more than 50% of the time maybe?).

[juba]

Damn, that's quite a problem if it happens half of the time... The issue is that it doesn't seem to happen on my system, so I can't reproduce it and try to find the cause.

Could you give me some more information, specifically:

• your R version
• the output of sessionInfo()
• how is the explor interface displayed : in the Rstudio viewer pane ? In an external browser ?
• how do you "exit" explor ? By closing the window ? By clicking the "stop" icon of the viewer pane ?

Thanks !

[gabrielparriaux]

I’m using R 4.3.0.

Here is the output of sessionInfo()

Explor interface is displayed in a new window in RStudio.

I exit by clicking the close button (red button in the corner of the window) or using shortcut cmd + w (on Mac). The problem appears when I quit both ways.

Hello @juba,

Long time no see (my first comment/issue on Github was on your amazing package ~10 years ago; so commenting now is "special" for me haha).

Anyway, I think the problem might be specific to macOS (or maybe depending on the browser people use on their computer), because when I use shiny apps on my computer (running on macOS with Brave browser), if I don't put the following code line in the server part of my shiny apps, I get the same problem as @Chatoranga and @gabrielparriaux :

server = function(input, output, session) {

session$onSessionEnded(function() { stopApp() }) #Stops the app when closing web browser

#... and the code of your shiny app here afterwards

}

Try to implement this line inside the server function, and tell me to test it, and I will tell you if the problem is solved. Then if @Chatoranga or @gabrielparriaux could confirm, the issue could be closed.

Thanks in advance for your response,
Best regards,
