Hi Roey,
It's not clear what you expect should happen when you dodge the
labels. Can you give a reproducible example and more clearly state
what result you're looking for?
Also, I've changed the subject line as this seems to be different
issue than the OP described.
Best,
Ista

Hi Ista,
Thanks for the quick reply.
What I'd like is for the text labels to not overlap each other as they do at the moment.
That is, I'd like the position to be roughly what is given by X and Y but then to be shifted somewhat so that the labels have a minimal overlap.
I thought that's what position_dodge is supposed to do; isn't it?!
Thanks again,
Roey

Hi Roey,
Someone may correct me, but I don't think position_dodge is up to the
task. Your best bet is probably the directlabels package -- see
http://drunks-and-lampposts.com/2012/02/22/labelling-a-ggplot-scatterplot/
for an example.
Best,
