Hi,
I am facing the issue in the package installation of "Rcmdr".
The error is showing
Loading required package: effects
Error: package or namespace load failed for ‘effects’:
.onAttach failed in attachNamespace() for 'effects', details:
call: RStudioGD()
error: Shadow graphics device error: r error 4 (R code execution error)
Error: package ‘effects’ could not be loaded
In addition: There were 50 or more warnings (use warnings() to see the first 50)
