[R] Alpha not working in geom_rect

[Adel]

Hi 
I am trying to activate the alpha argument to work, but for some reason it
does not to play with me. Anybody has an idea why?


p <- ggplot(data = prediction_df, aes(x=x, y=prediction, fill=threshold)) +
geom_area(colour="black", size=.2, alpha=.4) +
scale_fill_brewer(palette="Set1",
breaks=rev(levels(prediction_df$threshold)))
p + geom_rect(aes(xmin=2, xmax=10, ymin=(0), ymax=(1)), fill="black",
alpha=0.5)
