Adding a normal density curve over the empirical curve
...on of the two. Does anyone know how to do this?
(NB the last two lines are the problem, and are wrong, I know).
Thank you in advance!

How can I avoid nested 'for' loops or quicken the process?
Hi All,
I'm still pretty new to using R - and I was hoping I might be able to get
some advice as to how to use 'apply' or a similar function instead of using
nested for loops.
Right now I have a script which uses nested for loops similar to this:
