This is primarily used for aligning points generated through
geom_point()
with dodged boxplots (e.g., a geom_boxplot()
with
a fill aesthetic supplied).
position_jitterdodge(
jitter.width = NULL,
jitter.height = 0,
dodge.width = 0.75,
seed = NA
)
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 position_dodge()
width.
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 NULL
to use the current random seed and also avoid resetting
(the behaviour of ggplot 2.2.1 and earlier).
