[R] log y 'axis' of histogram

That doesn't justify the use of a _histogram_  - and regardless of
what distributional display you use, logging the counts imposes some
pretty heavy restrictions on the shape of the distribution (e.g. that
it must not drop to zero).

It may be useful for your purposes, but that doesn't necessarily make
it a meaningful graphic.
