How does one overcome overlapping points without jitter or transparency in ggplot2

Question

I am starting to use ggplot2. I have some small n (about 30 or so) granular data with lots of overlap. Neither jitter nor alpha (transparency) are suitable. Instead a stripchart

Answer 1

You want to use geom_dotplot from ggplot2

you will probably want to use:

ggplot(insert your arguments here) + geom_dotplot(binaxis = "y", stackdir = "center")

Hope this helps. The results will look really clean which is what I think you want.
