Passing two parameter functions into apply

Say I have a function called 

myfun <- function(x,y) {median(x,y)} # obviously the actual function is 
                                     # something more complicated

Now lets say in a certain use, the y parameter is constant, (say c(1,2,3,4,5)). Is there any way I can pass this into apply without wrapping it in another function? i.e.
instead of 

apply(mydf, 2, function(x) myfun(x, c(1,2,3,4,5)))

to pass something like 

apply(mydf, 2, myfun(,(c(1,2,3,4,5))))

This is purely cosmetic and I know it won't make much difference to the running time. I just want to know if an option like this is possible because wrapping my function in a function each time seems inefficient

I think this should work:

apply(mydf, 2, myfun, y = c(1,2,3,4,5))

Remains untested as I can't access R right now.
