I have R.Studio 1.3.1093 with R 4.2.1 installed, but when lauching R.Studio I have this message : "R graphics engine version 15 is not supported by this version of RStudio. The Plots tab will be disabled until a newer version of RStudio is installed. "
I saw the other topics about this, and as they advisedy, I tried to install a development version of RStudio from this URL : https://dailies.rstudio.com/
The problem is that these version don't work on my mac. I'm on Mac OS 10.14.6
There is no need to install development versions of the IDE, the latest stable version already supports the new R graphics engine. But, the advertised support goes from macOS 10.15+. Are you able to update your Mac version?
