| position_jitter {ggplot2} | R Documentation |
Jitter points to avoid overplotting.
position_jitter(width = NULL, height = NULL)
width |
degree of jitter in x direction. Defaults to 40% of the resolution of the data. |
height |
degree of jitter in y direction. Defaults to 40% of the resolution of the data |
Other position adjustments: position_dodge;
position_fill;
position_identity;
position_jitterdodge;
position_stack
qplot(am, vs, data = mtcars)
# Default amount of jittering will generally be too much for
# small datasets:
qplot(am, vs, data = mtcars, position = "jitter")
# Control the amount as follows
qplot(am, vs, data = mtcars, position = position_jitter(w = 0.1, h = 0.1))
# With ggplot
ggplot(mtcars, aes(x = am, y = vs)) + geom_point(position = "jitter")
ggplot(mtcars, aes(x = am, y = vs)) + geom_point(position = position_jitter(w = 0.1, h = 0.1))
# The default works better for large datasets, where it will
# take up as much space as a boxplot or a bar
qplot(class, hwy, data = mpg, geom = c("boxplot", "jitter"))
