> Was wondering if it is possible to pass function name as a parameter
Yes. This isn't exactly what you wanted, but it demonstrates the
principle.
x = rnorm(5)
[1] -0.6510448 0.4591730 1.3225205 1.2314391 -0.0888139
myfun <- function(fname, x) eval(parse(text=paste(fname,"(x)",sep="")))
myfun('max',x)
[1] 1.322521
myfun('min',x)
[1] -0.6510448
