Hi,
I don't understand what
hist(x, freq=FALSE)
does.
At first I thought it would be just the relative frequencies instead
of the absolute frequencies,
by just computing "frequencies / n" in every category.
But with a small dataset the y-values (densities) don't sum to one.
Is there a way to get the histogram doing that?
Or what is the idea of this density-computation?
I hope the question is not too stupid...
It returns a probability density function, so the result integrates to
one. If the bars are chosen at unit spacings it will sum to one.
