Another question, in stripchart is there a way to draw a legends. I need legends that gives the mice count for each genotype wt/het/hom, something like the xyplot plot support for key/auto.key.

stripchart takes you almost all the way there:

with(dataFrame,

     stripchart(marbles_buried ~ genotype, 
                vert = TRUE, method = "jitter", 
                col = c('blue', 'red', 'green')))
meds <- as.vector(with(dataFrame, 
                       by(marbles_buried, genotype, median)))
segments((1:3)-0.25, meds, (1:3)+0.25, meds, col = c('blue', 'red', 'green'))
