R 3.0.x中的fill.contour引发错误 [英] filled.contour in R 3.0.x throws error
本文介绍了R 3.0.x中的fill.contour引发错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个自定义功能来绘制填充轮廓，该功能很大程度上基于Carey McGilliard和Bridget Ferris的工作( http://wiki.cbr.washington.edu/qerm/index.php /R/Contour_Plots .
I have a customized function for plotting filled contours which is heavily based on Carey McGilliard and Bridget Ferris work (http://wiki.cbr.washington.edu/qerm/sites/qerm/images/1/16/Filled.contour3.R) and http://wiki.cbr.washington.edu/qerm/index.php/R/Contour_Plots .
filled.contour3函数在R 2.15.3中可以完美运行，但在R 3.0.x中会引发错误.
the filled.contour3 function runs perfectly in R 2.15.3 but throws an error in R 3.0.x
Error in .Internal(filledcontour(as.double(x), as.double(y), z, as.double(levels), :
there is no .Internal function 'filledcontour'
能否请您提供解决方案或替代方案，以便我可以在R 3.0.x中使用filled.contour3()函数. * 我的大部分工作都取决于此功能，而我使用的是LInux，因此在生产机器上更改R版本并不是那么容易.会很乐意提供赏金. *
Could you please help me with a solution or a workarround so that I can use the filled.contour3() function in R 3.0.x . *A great deal of my work depends on this function and I am on LInux so changing R versions is not that easy on production machines. Will be happy to offer bounty.*

#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

推荐答案
如果使用非标准API，则会发生这种情况.您可以这样做，但不能期望它得到维护.
This happens if you use a non-standard API. You are allowed to do that, but cannot expect that it is maintained.
更改
.Internal(filledcontour(as.double(x), as.double(y), z, as.double(levels),
col = col))
到
.filled.contour(as.double(x), as.double(y), z, as.double(levels),
col = col)
更改已通过发行说明宣布:
基础图形的C代码已迁移到图形 包(因此不再使用.Internal()调用).
The C code underlying base graphics has been migrated to the graphics package (and hence no longer uses .Internal() calls).
您是否听说过最小可复制示例" (强调最小")?
