Package ‘ggh4x’ is not available (for R version 4.0.0)

[Spswitzer]

I would like to run the Shiny App that I created using, ggh4x, but I get the following error: package ‘ggh4x’ is not available (for R version 4.0.0).
The package suits my needs well, and I'd love to continue using it.

Could you please provide advice for resolving this error?

Thank you!

I'm not familiar enough with Shiny to be able to advice you on that, but I would presume an error like that would occur while trying to install ggh4x via CRAN. It's not on CRAN (yet), so if the app can only use CRAN packages, I'm afraid I cannot immediately help you.
