Yes, it's possible. See if this is what you want.
fun <- function(x, par1){
FUN <- match.fun(par1)
result <- FUN(x)
result
}
x <- c("a","b","a","c")
fun(x, max)
# using an unnamed function, 'y' is just a place holder
fun(x, function(y) length(unique(y)))
# using a named function
count.uniq <- function(y) length(unique(y))
fun(x, count.uniq)
Hope this helps,
