formatter argument in scale_continuous throwing errors in R 2.15

Question

Since upgrading to R 2.15, the formatter argument seems to be throwing errors. This was an argument that I've been using everyday for 2 years, so a huge bummer. R version 2.15.0 (2012-03-30) ggplot2 version 0.9.0 ``` > library(ggplot2) > x <- 1:100 > y <- 1/x > p <- qplot(x,y) > p + scale_y_continuous(formatter = "percent") Error in continuous_scale(c("y", "ymin", "ymax", "yend", "yintercept", : unused argument(s) (formatter = "percent") ```

Accepted Answer

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)
```
