Trying to run fancyrpartplot for the first time and encounter errors.
> fancyRpartPlot(rpart.sub1) Error in loadNamespace(name) : there is no package called 'rpart.plot'
I searched and searched, but cannot find a solution. I tried to remove the rattle and RGtk2 and keep getting the same errors. Think of something to do with GTK + but can't find anything that shows how to remove and reinstall GTK +

Interestingly, the file that it is talking about is missing C:/Program Files/R/R-3.1.0/library/RGtk2/libs/x64/RGtk2.dll , in fact, I checked it manually.
At this point, I deleted the rattle and RGtk2 several times. Every time RGtk2 installs GTK + again, but nothing changes.
Any help is greatly appreciated.
edit: It must have possibly added that if I rattle() , then the crack will load correctly.
