The easiest place to start when turning an exploratory graphic into an expository graphic is with good labels. You add labels with the labs()
function. This example adds a plot title:
ggplot(mpg, aes(displ, hwy)) +
geom_point(aes(color = class)) +
geom_smooth(se = FALSE) +
labs(title = "Fuel efficiency generally decreases with engine size")
Histogram and density plots
The histogram and density plots are used to display the distribution of data.
# Histogram plot
# Change histogram fill color by group (sex)
qplot(weight, data = wdata, geom = "histogram",
fill = sex)
# Density plot
# Change density plot line color by group (sex)
# change line type
qplot(weight, data = wdata, geom = "density",
color = sex, linetype = sex)
