[R] playing with R: make a animated GIF file...

you could first make the frames to put together in R, then outside of R glue the frames into a gif.

eg:

frames<-10
for(i in 1:frames) {

      jpeg(paste("ani_", i, ".jpg", sep = ""))
      plot(1:10,1:10, col = i)
      dev.off()

}

then use an image editing program to glue the jpgs together -- eg free and crossplatform imagemagick (www.imagemagick.org). under linux and once imagemagick is installed, the command

$ convert -delay 10 ani_*.jpg animation.gif

makes a looping animated gif `animation.gif' with 10/100 sec. between frame flips.
