R: plot3D scatter3D, 有没有 coord_fixed() 选项？

Question

我正在使用 ggplot2 和 plot3d 在 2D 和 3D 中绘制相同的散点图。我总是喜欢尽可能在 ggplot2 散点图中做 coord_fixed()，以获得更好的可读性。有没有办法在 scatter3D 情节中做同样的事情？

MWE：

data(iris)
head(iris)
library(ggplot2)
ggplot(iris, aes(x=Petal.Length, y=Petal.Width)) +
    geom_point(pch=16) + theme_light() + coord_fixed()
library(plot3D)
scatter3D(iris$Petal.Length, iris$Sepal.Length, iris$Petal.Width, bty = "u", pch = 16, alpha = 0.5,
          xlab = "Petal.Length", ylab = "Sepal.Length", zlab = "Petal.Width", phi = 0, theta = 40,
          col.panel = "white", col.grid = "gray", col="black", ticktype = "detailed")

Answer 1

scale = FALSE 这样做：

scatter3D(iris$Petal.Length, iris$Sepal.Length, iris$Petal.Width, bty = "u", pch = 16, alpha = 0.5,
          xlab = "Petal.Length", ylab = "Sepal.Length", zlab = "Petal.Width", phi = 0, theta = 40,
          col.panel = "white", col.grid = "gray", col="black", ticktype = "detailed",
          scale = FALSE)

来自 ?persp：

If scale is TRUE the x, y and z coordinates are transformed separately. If scale is FALSE the coordinates are scaled so that aspect ratios are retained
