You have not provided code to reproduce the problem so this will be just a guess.

I've used whitespace, \n in particular, to move text "away" in the past. Perhaps a custom formatter might work here. Here is how you can write a custom tick mark label formatter.

If this fails, you can always hide the axis labels and paint them yourself using geom_text by adding another layer.

Hope this helps. @hadley's book on ggplot2 is very good, by the way.
