##### Generate expansion vector for scales.

This is a convenience function for generating scale expansion vectors for the expand argument of scale_*_continuous and scale_*_discrete. The expansions vectors are used to add some space between the data and the axes.

##### Usage
expand_scale(mult = 0, add = 0)
##### Arguments
mult

vector of multiplicative range expansion factors. If length 1, both the lower and upper limits of the scale are expanded outwards by mult. If length 2, the lower limit is expanded by mult[1] and the upper limit by mult[2].

vector of additive range expansion constants. If length 1, both the lower and upper limits of the scale are expanded outwards by add units. If length 2, the lower limit is expanded by add[1] and the upper limit by add[2].

##### Examples
# NOT RUN {
# No space below the bars but 10% above them
ggplot(mtcars) +
geom_bar(aes(x = factor(cyl))) +
scale_y_continuous(expand = expand_scale(mult = c(0, .1)))

# Add 2 units of space on the left and right of the data
ggplot(subset(diamonds, carat > 2), aes(cut, clarity)) +
geom_jitter() +

# Reproduce the default range expansion used
# when the <U+2018>expand<U+2019> argument is not specified
ggplot(subset(diamonds, carat > 2), aes(cut, price)) +
geom_jitter() +
scale_x_discrete(expand = expand_scale(add = .6)) +
scale_y_continuous(expand = expand_scale(mult = .05))
# }
