单列的 3D 带状图

Question

我能够为矩阵创建 ribbon3D 图，该矩阵的行和列维度都大于 1。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，那么我的代码会出错。需要帮助解决这种情况。

给出一个table的样本数据如下：

    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")))

绘图使用的代码如下：

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)

对于那些对它如何处理大于 1 的矩阵感兴趣的人。这里是示例数据。但是在代码中将矩阵名称从 rs12 更改为 tf12。运行上述代码在上面示例中的错误是这样的，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, 
18, 18, 18, 40, 18, 18, 17, 36, 17, 39, 41, 17, 17, 17, 34, 38, 
36, 17, 34, 17, 17, 17, 40, 17, 17, 16, 38, 34, 40, 41, 16, 16, 
16, 16, 36, 36, 16, 34, 34, 34, 16, 39, 16, 16, 32, 40, 32, 40, 
41, 32, 32, 32, 14, 36, 36, 14, 14, 32, 32, 14, 38, 14, 14, 16, 
38, 33, 39, 41, 33, 16, 33, 33, 37, 36, 16, 33, 16, 16, 16, 40, 
16, 16, 14, 39, 31, 40, 41, 31, 31, 31, 31, 37, 36, 31, 14, 31, 
14, 31, 38, 14, 31, 30, 37, 30, 39, 41, 36, 13, 30, 30, 38, 30, 
30, 30, 30, 30, 30, 40, 13, 13, 15, 38, 32, 39, 41, 32, 15, 15, 
32, 38, 32, 32, 15, 32, 36, 15, 40, 15, 15, 15, 38, 32, 39, 41,

15, 16, 38, 34, 39, 41, 37, 16, 16, 34, 16, 34, 16, 16, 34, 34, 
16, 40, 16, 16), .Dim = c(19L, 11L), .Dimnames = list(c("Pig iron & spiegeleisen, sponge iron, powder & granu", 
"Ores and concentrates of base metals, n.e.s.", "Waste, parings and scrap, of plastics",

"2012", "2013", "2014", "2015")))

Answer 1

这是由 ribbon3D 中的错误引起的：它对矩阵进行子集化，但没有告诉 R 将其保留为矩阵，因此它变成了向量，之后事情变得很糟糕。

您可以使用 fix() 功能自行修复该错误，对其进行编辑并创建本地副本，但您最终会遇到不同的错误，很可能是由其他地方的相同问题引起的。

我建议你有两个选择：

花一些时间追踪并解决所有这些问题。这是学习 R 调试的好机会，但需要一段时间。将它们全部修复后，将必要更改列表发送给 plot3D 包的维护者。
写信给维护者，包括你的可重现的例子，希望她有兴趣和时间来解决这个问题。
