R：plot3D scatter3D，是否有coord_fixed（）选项？

Question

我正在使用ggplot2和plot3d在2D和3D中进行相同的散点图。我总是喜欢在coord_fixed()散点图中做ggplot2，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？谢谢

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)

如果scale为TRUE，则分别转换x，y和z坐标。如果scale为FALSE，则缩放坐标以保留纵横比
