嘗試首次運行fancyrpartplot並出現錯誤。r撥浪鼓fancyrpartplot錯誤
> fancyRpartPlot(rpart.sub1)
Error in loadNamespace(name) : there is no package called ‘rpart.plot’
我已經搜索和搜索，但找不到解決方案。我嘗試刪除撥浪鼓和RGtk2，並繼續得到相同的錯誤。認爲它是與GTK +，但無法找到任何說明如何刪除並重新安裝GTK +

IN ANY CASE, RESTART R BEFORE TRYING TO LOAD THE PACKAGE AGAIN

有趣的是，它說缺少C:/Program Files/R/R-3.1.0/library/RGtk2/libs/x64/RGtk2.dll的文件實際上是存在的，我已經人工檢查。
在這一點上我已經幾次刪除撥浪鼓和RGtk2。每次RGtk2再次安裝GTK +，但沒有任何變化。
任何幫助非常感謝。
編輯：應該有可能補充說，如果我輸入rattle()撥號似乎正確加載。
安裝軟件包rpart和rpart.plot – phiver
@phiver'plot（rpart.sub1）'正確繪製了rpart創建的樹，所以我知道rpart和rpart.plot都安裝並正常工作。 –
@SC。 plot（rpart.sub1）並不意味着rpart.plot可用。它只是繪製了rpart.sub1。使用rpart.plot進行繪圖意味着使用命令prp（或rpart.plot :: prp（rpart.sub1） – phiver
