Also, if it is not homework, why are you reinventing some functionality
already in R? R can easily calculate medians for you.

Did you try what I suggested?
If you go to www.rseek.org and search for "odd or even integers" you
will get various solutions.
You could even write your own test by comparing x/2 with round(x/2).
Also, it's good form to copy the list on your replies, not just me.

I can't find it that thing. And its not a homework task, I work for a company
who require this function to do analysis on some data but we're all new to R?

I've tried the if function? Its just defining when something is even or odd?
R's help system might be useful. www.rseek.org might be useful.
You haven't accomplished the second part of my response, and this
isn't a homework help list, so you'll need to do your own work from
here.

I'd start by using if().
If you can convince the list that this isn't homework, you might get more help.

Hi just a quick question in which I must use the "function and return" part of
R.
If I was asked to define a function called "median" where the function has a
single argument x and returns the median value of a vector. How would I go about saying
the median = element x in terms of n (say (n + 1)/2 or whatever it would be) if there is
an even amount of elements, or x in terms of n (with a different way of saying how many
n) if there is an odd amount of elements?
Much appreciated
