well, :-) 
you have not yet seen the following one :

if(!require("sfsmisc")) install.packages("sfsmisc")
require("sfsmisc")

## the data:
       set.seed(1); summary(x <- rlnorm(100, m = 2, sdl = 3))
## the plot (w/o  x-axis) :
       r <- hist(log10(x), xaxt = "n", xlab = "x [log scale]")
## the nice axis:
       axt <- axTicks(1)
       eaxis(1, at = axt, labels = pretty10exp(10^axt, drop.1=TRUE))
