#同时出现图1，选第一个 然后安装出现下面的代码
  Learn more about GTK+ at http://www.gtk.org
If the package still does not load, please ensure that GTK+ is installed and that it is on your PATH environment variable
IN ANY CASE, RESTART R BEFORE TRYING TO LOAD THE PACKAGE AGAIN
Warning message:
Failed to load RGtk2 dynamic library, attempting to install it.

安装时提示gtk有问题，后来永和推荐这个 ：R for macOS Developers 下载了最新的 GTK_2.24.17-X11.pkg (ca. 41MB),直接官网下载了安装包

本地安装方法 ：

还是不行:

那就代码直接安装

还是不行，结果提示版本不合适，over

结论

mac不可以安装，windows才行 真是两行泪，但是window系统的同道们可以参考这篇文章安装R的机器学习GUI工具rattle包 - 知乎
