Question

我能够为行和列的尺寸大于1的矩阵创建ribbon3D图。当其中一个维度为1时，我遇到了一个问题。这意味着如果我有12行和一列，则我的代码给出了错误。需要帮助解决这种情况。

表的示例数据如下：

    structure(c(3, 4, 2, 2, 9, 6, 6, 7, 8, 10, 11), .Dim = c(1L, 
11L), .Dimnames = list("Fruits and nuts (excluding oil nuts), fresh or dried", 
    c("2005", "2006", "2007", "2008", "2009", "2010", "2011", 
    "2012", "2013", "2014", "2015")))

用于绘图的代码如下：

library(plot3D)

ribbon3D(x = 1:nrow(rs12), y = 1:ncol(rs12), z = rs12, scale = T, expand = .2, bty = "b", along = "y",  
         colvar = rs12, colkey = F, border = "black", shade = 0.1, 
         theta = -50, phi = 40, space = .5, d = 2, 
         curtain = T, xlab = "", ylab = "", zlab = "", main = "Pakistan's Exports to Russia", 
         cex.axis = 0.000000000001, box = F)

对于那些对大于1的矩阵如何工作感兴趣的人。这是示例数据。但是在代码中将矩阵名称从rs12更改为tf12。通过在上面的示例上运行上面的代码而导致的错误是这样的，Error in persp.default(plist$xlim, plist$ylim, z = matrix(nrow = 2, ncol = 2, : increasing 'x' and 'y' values expected。

dput(tf12)
structure(c(18, 36, 18, 39, 41, 18, 18, 18, 18, 36, 37, 18, 38,

Answer 1

这是由ribbon3D中的一个错误引起的：它是一个矩阵的子集，但是没有告诉R将其保留为矩阵，因此它变成了向量，之后情况就很糟了。

您可以使用fix()函数自己编辑该错误，然后编辑并创建本地副本，但最终会出现一个不同的错误，很可能是由其他地方的相同问题引起的。

我建议您有两个选择：

花一些时间来查找和解决所有这些问题。这是学习R中调试的好机会，但需要一段时间。修复所有问题后，请将必要的更改列表发送到plot3D软件包的维护者。
写给维护者，包括您可以复制的示例，并希望她有兴趣和时间来解决此问题。
