Cool Tip Yihui,
Please consider also showing how to use this in conjecture with the tools you mentioned in the post, through R:
ImageMagick, OpenBUGS

p.s: consider using the "subscribe to comments" plugin :)

Cheers,
Tal

Thanks for your suggestion! The RSS icon in the address bar of Firefox will show the link to subscribe to comments (Firefox can detect RSS links in a page automatically).

I'll add two examples later.

Regarding the examples - Great!

Regarding the plugin - it allows people to subscribe using e-mail (that thing that people who don't know what RSS is use). My experience is that it is very useful for readers...

Cheers,
Tal

Hi, here is the code you have to use on Windows

    if (nzchar(magick.path) && require(animation)) {
            convert = shQuote(normalizePath(file.path(magick.path, "convert.exe")))
 
            ## record the demo 'recur.tree' in png images
            png("magickEx%d.png")
            demo(recur.tree)
           dev.off()
 
            ## call convert.exe to convert png images to GIF
            shell("convert -delay 20 -loop 0 magickEx*.png magickEx.gif")

             }

          file.remove(list.files(pattern=".png"))

If you´re using windows you have to use the shell function instead of system

Really? I switched back and forth between shell() and system() for several times when I was writing the function saveGIF() in the animation package. Finally I thought system() should be safe enough to call convert.exe under Windows. Anyway, if you want to use shell() in saveGIF(), you can specify it as saveGIF(..., cmd.fun = shell) after library(animation).
