Error in if: the condition has length > 1.

[Lekmonm]

When loading my shiny application, for the output of ggplotly, the shinyapps.io log gives me the following message: Error in if: the condition has length > 1.

I have checked why this message occurs and I saw that it is associated with the use of if(), but that it is solved with ifelse(); in my code, I only use ifelse(), but to generate the output of ggplotly, I do not use ifelse(), so I do not understand where the error can be.

I am grateful if you can guide me to solve this.

Hi, welcome!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at these resources, to see how to create one for a shiny app

Shiny debugging and reprex guide

Shiny issues can be challenging to resolve relative to other problems with your code or statistical methods. Shiny apps are often large, complex projects with interacting files. When seeking help from others it is considered polite to: First, do your best to work through RStudio's debugging tools to diagnose your issue on your own. Often those shiny logs and tracebacks are useful to others trying to help out. Second, strive to minimize the effort required to replicate your issue. You can do this with a reproducible example ("reprex"). Shiny Debugging Errors in Shiny code can be difficult to track down. If you don't know where your problem is coming from, you can track it down with some o…

I'm getting exactly this same error, Lekmonm!
Have you ever find out what causes it and how to solve it ?

Feel free to share your own reproducible example of the issue.

Hi, you probably have a logical vector with length > 1 (as a condition), try all() or any() or something similar.

Thank you for caring, nirgrahamuk, but for a newcomer to both R and Shiny, making my first app is challenging enough, I would probably waste too much time trying to build a reprex. If I don't find a solution I'll try it! Thanks
