I got ImageMagick working on Windows. The only problem occurred when I tried to write the movie file to a directory with subdirectories in it. It works with an empty directory, though.
I think it should be possible to incorporate the code from ImageMagick or GraphicsMagic into an R package, making an external install unnecessary.

For the community: I've successfully installed ImageMagick on Mac OS 10.6.4 (i.e. the sample commands to verify functionality check OK: http://www.imagemagick.org/script/binary-releases.php?ImageMagick=cmdb7qc5snnquootuef90ki645#macosx). I receive an error running Jacob's example code: Error in cmd.fun(sprintf("%s --version", convert), intern = TRUE) : error in running commandsh: convert: command not found I don't believe this is an 'animate' issue, but is a thorny path problem that apparently plagues ImageMagick installs via MacPorts. I tried some things based on the message boards at ImageMagick without success. This isn't the place for ImageMagick troubleshooting, but a heads up for Mac users trying to implement Jacob's example...

It´s actually quite simple. library(raster) library(animation) setwd("c:/empty") logo <- raster(system.file("external/rlogo.grd", package="raster"), values=TRUE) saveMovie( for(i in 1:250) { logo1 <- logo logo1[logo1<i] <- 0 #here you could also extract a RasterLayer from a RasterStack plot(logo1, main=i) }, loop=1, interval= 0.1, outdir = getwd(), moviename="logo") Cheers, Jacob. --- On Sat, 13/11/10, Kevin Ummel <kevinum...@gmail.com> wrote: From: Kevin Ummel <kevinum...@gmail.com> Subject: [R-sig-Geo] Anyone attempted to "animate" multi-layered rasters? To: R-sig-Geo@stat.math.ethz.ch Date: Saturday, 13 November, 2010, 12:58 Hello, I came across the 'animate' package, and I'm wondering if anyone has successfully adapted it to create animations of multi-layered spatial data. This seems like a logical advance of R's spatial data visualization, especially given the prominence of NetCDF and HDR file types, but I don't want to replicate if someone else already has a function in working order...
