R help - Jan 2012 - how do I make a movie out of a timeseries of 2D data?

Hi all,

I have an array of 10000 x 200 x 200 numbers... which is a time-series of
200x200 2D data...

The 1st dimension is the time index.

Is there a way to make a movie out of these data - i.e. playback 10000
frames(200x200) at a playback rate per second?

Thanks a lot!

Michael,

Please don't cross post to both lists.  If it doesn't have to do with
finance, don't send it it r-sig-finance.

Thanks,
Garrett

I'd use R to create the sequence of images you need (named sequentially),
then use ImageMagick's animate function.
http://www.imagemagick.org/www/animate.html

But you don't tell us what you are trying to do, so I have no way of knowing
if that will work for you.

If you need the animation in a file outside of R (or possibly in R) then look at
the animation package.  This allows you quite a few options on how to save an
animation, some of which depend on outside programs, but options mean that if
you don't have one of those programs there are other ways to do this.

If you just want to explore this within R then the development version of the
TeachingDemos package (on R-Forge) has added an animate control to the tkexamp
function.  Just create a function that takes the time index as the argument and
creates the plot you want for each time, then run tkexamp using the animate
control for the time argument.  You will see a new window with the plot for the
1st time index along with a slider that will let you move through time and a
button that will step through the remaining times automatically (you can specify
the speed when running tkexamp).

Is there a way to make a movie out of these data - i.e. playback 10000
frames(200x200) at a playback rate per second?

Thanks a lot!
