You can use ImageMagick tools to convert a set of bitmap files into an animated GIF. For example, in R, this creates 101 separate png files:

x <- seq(-1,1,length=101)
y <- x^2
for (i in 1:length(y)) {
  plot(x[1:i], y[1:i], xlim=c(-1,1), ylim=c(0,1), type="l") }

Then, on the command line (on Linux) this joins them together

convert -delay 10 Rplot*.png Rplot.gif
animate Rplot.gif

You can also create MNG format, but this is less widely supported.
