Can you use this with ggplot2?

How can change the saving folder? movie.name = "subfolder/animation.gif" doesn't work.

Yihui, how do we think about the upper limit of how many frames we can stitch together with saveGIF() ? Take the code below for example:

nframes<-1000
saveGIF({
for (i in 1:nframes) plot(runif(10), ylim = 0:1)
})

I can get it to work for nframes = 300 but not for nframes=400 or anything bigger. Somewhere between 300 and 400 is its apparent limit. As I understand it ImageMagick's limit is close to 10,000, so that does not appear to be the binding constraint. Is there a solution to it? Or is there another way to save the video (other than saveGIF) that would allow stitching of more frames?

Yihui, I went through your example - demo('rgl_animation') - which saves a sequence of png frames of rgl scenes (created with rgl.snapshot) as a Latex document. I am wondering if these rgl scenes could instead be saved as a video file with saveGIF() perhaps. Is it possible? Or pehaps more broadly, how could I stitch the (rgl scenes) frames below into a video using the animation package?

for (i in 1:10) {
with(iris, plot3d(x=Sepal.Length[i], y=Sepal.Width[i], z=Petal.Length[i], type="s", col=as.numeric(Species)))
}

Thank you.

最后一个示例我这里会报错，报错日志如下：

错误于if (100%%fps) stop("argument 'fps' must be a factor of 100"): 
  the condition has length > 1
animation option 'nmax' changed: 30 --> 50
