The error is from the scale_y_continuous
call. Formatting of labels is now handled by the labels
argument. See the ggplot2 0.9.0 transition guide for more details.
There was another problem with the labels not lining up correctly; I fixed that by adding a group=B
to the aesthetics for the geom_text
; I’m not quite sure why this is necessary, though. I also took out x=A
from the geom_text
aesthetics because it was not needed (it would be inherited from the ggplot
call.
library("ggplot2")
library("scales")
ggplot(data=df, aes(x=A, y=Freq))+
geom_bar(aes(fill=B), position = position_dodge()) +
geom_text(aes(label = paste(sprintf("%.1f", Freq*100), "%", sep=""),
y = Freq+0.015, group=B),
size = 3, position = position_dodge(width=0.9)) +
scale_y_continuous(labels = percent) +
theme_bw()
