formatter argument in scale_continuous throwing errors in R 2.15

The syntax has changed with version 0.9.0. See the transition guide here: https://github.com/downloads/hadley/ggplot2/guide-col.pdf

library(ggplot2)
library(scales)
x <- 1:100
y <- 1/x
p <- qplot(x,y) + scale_y_continuous(labels  = percent)
