Is ther a possibility to display the log(frequency) instead of the frequency in the hist plot?
The only potential problem with this solution is that bins with zero counts and bins with 1 count will both be treated as zeros. Consider: my.data <- c(1.5,1.5,2.5,4.5,5.5,5.5) my.hist.counts <- hist(my.data, plot=F, breaks=0:6)$counts etc. This is an unlikely event with the default "breaks" settings, though. (On the other hand, the fact that you have bins with zero counts says that you might well have bins with only 1 count.) Ben

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");

Some questions still remain to me. 1. How take an log if one of the my.hist$counts equals 0?
