I have problems getting a histogram with relative frequencies on the y-axis.
Here is an example data set:
> a <- c(4.626, 4.627, 4.627, 4.628, 4.629, 4.629, 4.630, 4.631, 4.632,
4.632)
> d = hist(a,freq=F)
> d$density
[1] 299.9999 100.0000 200.0000 100.0000 100.0000 200.0000
The obtained densities are given by counts/(total n * bin width), with
bin width being 0.001 in this case.
Is there any way to get a histogram with relative frequencies
irrespective of bin width, i.e. counts/total n ? It doesn't seem to work
for truehist() either.
Thanks.
Steffen
