R help - Sep 2005 - Log scale in histograms

Can't find any information about this, but others must want to do it.

In the example below, the second plot has the desired log scale, but the
first does not.

Any help appreciated.

data(state)
area_Mh = 259*state.area/1000000

histlogarea = hist(log(area_Mh), 13, xlab="Area (Mh)",
main="")
histlogarea$mids = exp(histlogarea$mids)
histlogarea$breaks = exp(histlogarea$breaks)

plot(histlogarea, log="x")

plot(histlogarea$mids, histlogarea$density, log="x")

Well, I had to solve this problem myself.  I hope that doesn't prove I
should have posted it.  I did spend a lot of time on it, both before and
after posting.

Here is a reasonable-looking histogram based on logged data:

hist(log10(area_Mh), 12, xlab="Area (Mh)", main="",
axes=FALSE)
axis(1, labels=formatC(10^(axTicks(1)), digits=3))
axis(2)
