为什么我的 3D 绘图没有显示在 R Studio 绘图查看器中？

Question

我通常在 RStudio（版本 1.0.44）中查看绘图时没有问题，但是当我尝试查看使用 "rgl" 包创建的 3D 绘图时，我的 RStudio 绘图查看器中没有任何显示.

我可以毫无问题地绘制 plot(cars) 散点图。

这是我使用的代码：

install.packages("rgl")
library(rgl)

plot3d(iris[1:3])  # Nothing appears in RStudio plot viewer

plot(cars)  # The cars scatterplot appears in my RStudio plot viewer
dev.off()

知道为什么会这样吗？我还应该尝试什么？当我运行 plot3d(iris[1:3]) 时，我没有收到任何错误。我检查了 head(iris[1:3]) 以确保我正确加载了虹膜数据。我也试过改变情节边距：

par(mar=c(4,4,4,4)

谢谢

Answer 1

"Output may be on screen using OpenGL, or to various standard 3D file formats including WebGL, PLY, OBJ, STL";
"There are two ways in which rgl scenes are normally displayed within R. The older one is in a dedicated window. In Unix-alikes this is an X11 window; it is a native window in Microsoft Windows. On MacOS, the XQuartz system (see http://xquartz.org) needs to be installed to support this."
"The newer way to display a scene is by using WebGL in a browser window or in the Viewer pane in RStudio. To select this, set options(rgl.printRglwidget = TRUE). Each operation that would change the scene will return a value which triggers a new WebGL display when printed."

文档 FTW
