Dear All,
I am not sure that R is exactly the right tool for doing what I have in mind, but a look at EBImage and rimage convinced me that this should be doable with R. I have a color image and I would like to do the following: convert the image into a grayscale image retaining only the red color (i.e. end up with a grayscale image where the only surviving color is red [or any color close enough to red]).
Anybody has any idea about how to do that?
Many thanks

Lorenzo
