if you want the "frequency" scale rather than density scale, then leave
hist as is (by default it uses the frequency scale), and rescale the
density by multiplying it by the appropriate NOBS.

Hi
Thank you very much for taking time to answer.
The solution of using hist(data) for the main dataset and adding
lines(density(refdata)) for the reference data seem to work great. I
forgot to mention one thing however, I need to have frequency on the y
azis instead of density as now.
I know this is not a "real" histogram but since the audience is not
very statistically experienced I would prefer to do it this way.
Anyone have an idea?
Thanks again for your help.

I don't understand this. Why not just get hist() to plot on the
density scale,
thereby making its output commensurate with the output of density()?
The hist() function will plot on the density scale if you ask it to.
Set freq=FALSE
(or prob=TRUE) in the call to hist.
ehrm... because i didn't realize that option existed :) that certainly is
easier than manually scaling hist output by NOBS - thanks for the tip!
