Simultaneously dodge and jitterSource:
degree of jitter in x direction. Defaults to 40% of the resolution of the data.
degree of jitter in y direction. Defaults to 0.
the amount to dodge in the x direction. Defaults to 0.75, the default
A random seed to make the jitter reproducible. Useful if you need to apply the same jitter twice, e.g., for a point and a corresponding label. The random seed is reset after jittering. If
NA(the default value), the seed is initialised with a random value; this makes sure that two subsequent calls start with a different seed. Use
NULLto use the current random seed and also avoid resetting (the behaviour of ggplot 2.2.1 and earlier).
