R help - Feb 2009 - Reading images

Hi

Can anyone tell me how to convert an image file (a jpg file for instance)
into a matrix file?

The command image(blabla) transforms a matrix into an image file, I am
searching exactly the inverse.

Thanks...

There's lots of info in the mailing list archives on this topic - 2 minutes
with
google would have gotten you to read.jpeg and saved you some time.
