Dear R-users,

In advance excuse me for this basic question. I´m trying to compare the
coloration patterns on three spider species. In order to do that, I was
trying to convert the image on a pixel matrix and compare them.

Because of that, I´d like to know how to convert an image to a pixel matrix
and if there exists some way to find the color frequency and distribution
on the pictures using R. I have found some posts to make the opposite
procedure but no this specifically.

Thanks a lot, any help wll be greatly appreciated!
