can't install rattle on Mac OS

[Qiang Shen]

Previously I have successfully installed the rattle on my computer, but still failed this time. I am a Mac user (10.12.6) and the R version is 3.4.1, I have installed Xquartz and the latest version of the GTK (GTK_2.24.17-X11.pkg), but still fail to install RGtk2 using the command install.packages("RGtk2", depen=T) in R(see below for the detailed inforamtion), then how I can solve this?

Btw, as the rattle is a tool that aim to make it easier to run the machine learning analysis using GUI in R, it's vital to make the installment as painless as possible, or it will be quite hard to make is popular among general users.

Users of Mac OS/X might be interested to know that Yihui Xie of RStudio has set up a repo for the Mac that simplifies installing rattle. Have a look at https://zhiyzuo.github.io/installation-rattle/
