Examples

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"))
