How to override ggplot2's axis formatting?

Question

When you choose a log scale, ggplot2 formats the breaks like 10^x. I'd like it to not do that. For example, the code below should display a graph with ticks at 1, 2, 5 etc, not 10^0, 10^0.3, 10^0.69 etc.

library(ggplot2) dfr <- data.frame(x = 1:100, y = rlnorm(100)) breaks <- as.vector(c(1, 2, 5) %o% 10^(-1:1)) p1 <- ggplot(dfr, aes(x, y)) + geom_point() + scale_y_log10(breaks = breaks) print(p1)

I guess that adding a formatter argument to scale_y_log10 would do the trick, but I'm not sure what to put in the argument, or where the options might be documented.

scale_y_log10(breaks = breaks, labels = breaks should do the trick.

As of ggplot2 version 0.9.0, this behavior (formatting the axis labels as 10^0) is no longer the default. The code in the question now gives the desired result.

library(ggplot2) dfr <- data.frame(x = 1:100, y = rlnorm(100)) breaks <- as.vector(c(1, 2, 5) %o% 10^(-1:1)) p1 <- ggplot(dfr, aes(x, y)) + geom_point() + scale_y_log10(breaks = breaks) print(p1)
