What would it mean?  First, hist gives a density, so plotting on a log x
scale is not correct: you would want the density of log x, not x, and you
cna of course get that by hist(log(x)). Second, if you want to plot a log
density, you should use a better density estimate, one that does not return
0, for example.

If perchance what you are calling hist on is a discrete variate, you should
not be using hist ....

As ever, we suggest you keep R up to date. 1.2.1 is due tomorrow.
