R help - Mar 2005 - png device & videos

Hi all;

please, has anyone found a way to convert a series of png files created in an 
R script into a video (as avi), from within the same R script?

I know this has little relation with typical R problems. Just because I've 
spent all day without finding a solution, and perhaps anyone has done it 
before here.

Thanks and best regards,

Javier

I have not done it personally, but there are several Linux based apps
that can take PNG/JPGs and convert them to MPG/AVI. This is not within
R, but external to it.

Your e-mail header suggests that you are using KDE, so you might want to
look at:

I believe that the mencoder application can also do this. It is
available via the MPlayer site. More information is available here:

You might want to do a Google search to find additional options.
