R中的多個輪廓圖

Question

從這里實現代碼時我遇到了問題。 錯誤消息如下。

.Internal錯誤（filledcontour（as.double（x），as.double（y），z，as.double（levels），：沒有.Internal函數'filledcontour'

我所做的只是副本，這三個文件粘貼到一起，即filled.contour3.R，filled.legend.R和例4面板輪廓與一個legend.R情節在這里 。

最初，我認為這是因為fillcontour應該被填充.contour 。 但是，在此更改后，彈出幾乎相同的錯誤消息。 或者這可能是一些版本問題，因為代碼是在2010年編寫的。有誰能告訴我為什么我有這樣的問題以及如何解決它，好嗎？

Answer 1

粘貼代碼非常有用。 看起來fill.contour的方式發生了變化，因為該代碼首次發布。 改變線

.Internal(filledcontour(as.double(x), as.double(y), z, as.double(levels), 
       col = col))

至

.filled.contour(as.double(x), as.double(y), z, as.double(levels), 
       col = col)

這樣做我得到了情節
