Gurus,
beginner here. I tried to initiate rattle but it returned this:
The RGtk2 package is not available but is required.
Please install the package using, for example:
install.packages("RGtk2")
then I tried to install RGtk2 and Rstudio returned this:
package ‘RGtk2’ is not available for this version of R
I also tried downloading RGtk2 from here:
https://cran.r-project.org/src/contrib/Archive/RGtk2
but when I rattle() it returned this:
package ‘RGtk2’ was installed before R 4.0.0: please re-install it
Is rattle obsolete or did I miss anything? Thanks in advance!
