r rattle fancyrpartplot 错误

Question

第一次尝试运行 fancyrpartplot 并且运行出错了。

> fancyRpartPlot(rpart.sub1)
Error in loadNamespace(name) : there is no package called ‘rpart.plot’

我找了又找，但找不到解决方案。我尝试删除 rattle 和 RGtk2 并不断收到相同的错误。认为它与 GTK+ 有关，但找不到显示如何删除和重新安装 GTK+ 的任何内容

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

有趣的是，它说的文件丢失 C:/Program Files/R/R-3.1.0/library/RGtk2/libs/x64/RGtk2.dll 实际上是存在的，我手动检查过。

至此，我已经多次删除了 rattle 和 RGtk2。每次 RGtk2 再次安装 GTK+ 但没有任何变化。

非常感谢任何帮助。

编辑：如果我键入 rattle() 拨浪鼓似乎可以正确加载，可能应该补充一下。
