Sorry if this topic has been discussed earlier.
Currently, hist(..., log="y") fails with
> hist(rexp(1000, 1), log="y")
Warning messages:
1: In plot.window(xlim, ylim, "", ...) :
nonfinite axis=2 limits [GScale(-inf,2.59218,..); log=TRUE] -- corrected
now
2: In title(main = main, sub = sub, xlab = xlab, ylab = ylab, ...) :
"log" is not a graphical parameter
3: In axis(1, ...) : "log" is not a graphical parameter
4: In axis(2, at = yt, ...) : "log" is not a graphical parameter
The same applies for log="x"
> hist(rexp(1000, 1), log="x")
Warning messages:
1: In plot.window(xlim, ylim, "", ...) :
nonfinite axis=1 limits [GScale(-inf,0.954243,..); log=TRUE] -- corrected
now
2: In title(main = main, sub = sub, xlab = xlab, ylab = ylab, ...) :

4: In axis(2, at = yt, ...) : "log" is not a graphical parameter
This applies for the current svn version of R, and also a few recent
published versions. This is unfortunate for two reasons:
* the error message is not quite correct--"log" is a graphical parameter,
but "hist" does not support it.
* for various kinds of data it is worthwhile to make histograms in log
scale. "hist" is a very nice and convenient function and support for log
scale would be handy here.
I also played a little with the code, and it seems to be very easy to
implement. I am happy to make a patch if the team thinks it is worth
pursuing.
Cheers,
Ott
