You might find it easier to do this type of thing with an open-source image
analysis program such as ImageJ: http://rsb.info.nih.gov/ij/

Subject: [R] cell counting in R

> I have a bunch of jpg files that I need to count cells on.  Some cells are
green and some cells are red.  Is there a function like locator that I could
use to manually count the cells?  I would like to be able to click on a
cell, have it marked so I don't count it again and have a counter keep
track.  Locator comes close but I would only be able to count one colour at
a time.  Is there a way I can do this in R?
