在 R 的 3dplots 中更改轴标题和标签的方向？

Question

我有一个问题，对于 R plot 专家来说可能很容易。我需要在R中绘制3D图，我的数据如下：

df <- data.frame(a1 = c(489.4,  505.8,  525.8,  550.2,  576.6),
a2 = c(197.8,  301,    389.8,  502,    571.2),
b1 = c(546.8,  552.6,  558.4,  566.4,  575),
b2 = c(287.2,  305.8,  305.2,  334.4,  348.6), c1 = c(599.6,  611.4,  
623.6,  658,    657.4), c2 = c(318.8,  423.2,  510.8,  662.4,  656),
d1 = c(616,    606.8,  600.2,  595.6,  595),
  d2 = c(242.4,  292.8,  329.2,  378,    397.2),
e1 = c(582.4,  580,    579,    579,    579),
e2 = c(214,    255.4,  281.8,  303.8,  353.8))

colnames(df) <- rep(c("V1", "V2"), 5)
df.new <- rbind(df[, c(1, 2)],df[, c(3, 4)],df[, c(5, 6)],               
df[, c(7, 8)],df[, c(9, 10)])
df.new$Group <- factor(rep(c("a","b","c","d","e"), each = 5))
df.new$Class <- rep(c(1:5), 5)

我正在使用 scatterplot3d 包绘制 3D 图。

x=df.new$Class
y=V1
z=V2
scatterplot3d(x,y,z, pch = 16, color=colors,main="3D V1 v.s V2",xlab = 
"Class",ylab = "V1", zlab = "V2")

现在我想做2个修改。一个是使这些轴的垂直标题水平，下一个是为 x 值放置一个标签，例如为 x 值中的 1 放置一个标签 "first interval" 等等。我该怎么做？

另外，我怎样才能让点变成直线或平面而不是点。

Answer 1

One is to make the vertical title of those axis horizontal

为此，您需要隐藏当前标签，并使用 text() 函数在正确位置添加旋转标签；如此处所述

set.seed(42)
scatterplot3d(rnorm(20), rnorm(20), rnorm(20), ylab = "")
text(x = 5, y = -2.5, "Y-axis", srt = 45)

and for example put a label "first interval" for 1 in x values and so one and so forth. How an I do it?

来自文档 - https://cran.r-project.org/web/packages/scatterplot3d/scatterplot3d.pdf 使用 x.ticklabs 属性，例如：

xlabs <- c("first interval", "second", "third", "fourth", "this is 5")
scatterplot3d(x,y,z, pch =16,main="3D V1 v.s V2",xlab = "Class",ylab = "V1", zlab = "V2", x.ticklabs=xlabs)

Also, how can I make the points linear or plane instead of dots.

Scatterplot3d 提供"lines"和"vertical lines"，例如：

scatterplot3d(x,y,z , type="l", lwd=5, pch=" ")
#or
scatterplot3d(x,y,z , type="h", lwd=5, pch=" ")
