Histogram with “negative” logarithmic scale in R

Question

I have a dataset with some outliers, such as the following

x <- rnorm(1000,0,20)
x <- c(x, 500, -500)

If we plot this on a linear x a

Why suffer with ggplot2 solution? Your first plot was done with lattice histogram function, and this is where you should stay. Just apply logarithmic transformation directly within histogram function, use nint argument to specify the number of histogram bins, and type argument to choose between "count", or "density". I think that you got everything you need there, but maybe I'm missing some crucial detail of your question...

library(lattice)
histogram(log10(x), nint=50, type="count")
