我有一个用于绘制填充轮廓的自定义函数,该函数主要基于 Carey McGilliard 和 Bridget Ferris 的工作(http://wiki.cbr.washington.edu/qerm/sites/qerm/images/1/16/Filled.contour3.R ) 和http://wiki.cbr.washington.edu/qerm/index.php/R/Contour_Plots

filled.contour3函数在 R 2.15.3 中完美运行,但在 R 3.0.x 中引发错误

Error in .Internal(filledcontour(as.double(x), as.double(y), z, as.double(levels),  : 
  there is no .Internal function 'filledcontour'

您能否帮助我提供解决方案或解决方法,以便我可以使用filled.contour3()R 3.0.x 中的功能。*我的很多工作都依赖于这个函数,而且我在 LInux 上,所以在生产机器上更改 R 版本并不容易。将很乐意提供赏金。*

要重现错误,请首先获取以下内容

#Example Four Panel Contour Plot with One Legend
#Author: Carey R McGilliard
#September 2010

#This code uses a modified version of filled.contour called filled.contour3 (created by Carey McGilliard, Ian Taylor, and Bridget Ferris)
#to make an example figure of four contour plots sharing a legend (to the right).
#The example demonstrates how to use various color schemes for the contour plots and legend, but the user will want to
#pick one color scheme for all four plots such that the legend matches the plots.
#Changing the x- and y-axis values will change the placement of text added to the figure using the text() function and adjustments will be necessary


#Source the following functions (change the paths as necessary)
#source("./print.letterTrevor.R")

#gplots has the function colorpanel, which is handy for making gray-scale contour plots

如果您使用非标准 API,就会发生这种情况。您可以这样做,但不能期望它会得到维护。

改变

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

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

更改与发行说明一起宣布:

基本图形底层的 C 代码已迁移到图形包(因此不再使用 .Internal() 调用)。

您是否听说过“最小可重现示例”(强调“最小”)?
