[R] consolidate legends in ggplot2

the same parameter for colour and shape aesthetics gives 2 legends:

p <- ggplot(mtcars, aes(x=wt, y=mpg))
p + geom_point(aes(colour=factor(cyl), shape=factor(cyl)))

Can the 2 legends be consolidated to one with colours and shapes of the symbols matched between legend and plot ?

Thank you
