A function is not really necessary. 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.

Subject: [R-sig-Geo] Anyone attempted to "animate" multi-layered rasters?

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...
Cheers,
Kevin
