I have the following plot like below. It was created with this command:
df <- data.frame(cond = factor(rep(c("A", "B"), each = 200)),
rating = c(rnorm(200), rnorm(200, mean=.8)))
ggplot(df, aes(x=rating, fill=cond)) +
geom_density(alpha = .3) +
xlab("NEW RATING TITLE") +
ylab("NEW DENSITY TITLE")
Now next thing I want to do is to modify the legend title from cond into NEW LEGEND TITLE.
So what I did is to just add the following line add the end of the above code:
+labs(colour="NEW LEGEND TITLE")
But it doesn't work. What's the right way to do it?
