plot3d() produces a 3d plot that I can twist around and rotate. But when I call plot3d() again, the previous plot goes away and is replaced by this one.
How can I make it so that a new XQuartz window opens up rather than the old window being replaced by the new 3d plot.
Essentially, I want two 3d plots opened at once.
Answer
like this:
library(rgl)
open3d()
x <- sort(rnorm(1000))
y <- rnorm(1000)
z <- rnorm(1000) + atan2(x,y)
plot3d(x, y, z, col=rainbow(1000))
open3d()
x <- sort(rnorm(20))
y <- rnorm(20)
z <- rnorm(20) + atan2(x,y)
plot3d(x, y, z, col=rainbow(20))
The key here is calling open3d before the second plot to open a new "device"
