I imagine that the point of logging the histogram count axis is just for
displaying purposes, and your suggestion would alter the scale. I find it
easier to just leave the 0 counts as zero.
hist(my.data, plot=F)$counts -> my.hist.counts;
my.hist.counts[my.hist.counts != 0] <-
log(my.hist.counts[my.hist.counts!= 0]);
plot(my.hist.counts, type="hist");
