I tried to install R packages 'rattle' but when I typed
install.packages('rattle')
it returns
Warning in install.packages :
dependency ‘RGtk2’ is not available
So I tried install 'RGtk2',
install.packages('RGtk2')
it returns
Warning in install.packages :
package ‘RGtk2’ is not available (for R version 3.2.3)
My computer is windows 8.1, R version 3.2.3 and I'm working on the R studio.
One possible solution as mentioned is to install an older version of RGtk2. For Windows this might be:
install.packages("https://cran.r-project.org/bin/windows/contrib/3.3/RGtk2_2.20.31.zip", repos=NULL)
