Remove legend ggplot 2.2

Question

I\'m trying to keep the legend of one layer (smooth) and remove the legend of the other (point). I have tried shutting off the legends with guides(colour = FALSE)

Answer 1

from r cookbook, where bp is your ggplot:

Remove legend for a particular aesthetic (fill):

bp + guides(fill=FALSE)

It can also be done when specifying the scale:

bp + scale_fill_discrete(guide=FALSE)

This removes all legends:

bp + theme(legend.position="none")
