In ggplot2, this is done with the alpha argument. This argument can be used to make colors transparent by selecting the degree of transparency between 0 (completely transparent) and 1 (completely opaque). There are many possible applications of this argument, but for the time being, we will use the basic assignment in qplot(). Just remember that since this is an aesthetic parameter, you need to use the I() function, since we are not mapping something, but simply assigning a value of transparency.
