I'm having the same problem as Stephan (see below), but what I'm trying to jitter is not a numeric vector, but a factor. How do I proceed? (Naively jittering a factor makes it numeric, no longer factor, so I don't get the custom ordering which conveniently comes with using a factor. I'm not sure how I would simulate that custom ordering with the jittered vector ... I couldn't find anything online about jittering factors, but maybe I just wasn't searching cleverly enough.)
Incidentally, the reason I need to synchronize jittering, so to speak, is because I am using two geom_points to create the effect of a filled circle with a solid outline but a transparent fill. E.g., ggplot(data, aes(x_factor, y_numeric)) + geom_point(shape = 21) + geom_point(alpha = 0.5) Is there a more elegant way to accomplish this goal, or is using two geom_points the way I'm supposed to do it? hadley wickham wrote: > > On Sat, Sep 12, 2009 at 1:34 PM, Stephan Kolassa <stephan.kola...@gmx.de> > wrote: >> Dear guRus, >> >> I am starting to work with the ggplot2 package and have two very dumb >> questions: >> >> 1) deterministic position_jitter - the jittering is stochastic; is there >> any >> way to get a deterministic jittering?
