With the Force on your side, functions always do what you want.

Hi,
I am not sure what you are looking for. Here are some examples:
foo <- function(a,b,x) a + b*x
> foo
function(a,b,x) a + b*x
a <- 2
b <- 3
x <- 0:10
> foo(a,b,x)
[1] 2 5 8 11 14 17 20 23 26 29 32
Or
library(polynom)
p1 <- polynomial(c(a,b))
> p1
2 + 3*x
f1 <- as.function(p1)
> f1(

I don't want the function to depend on the objects a and b, but
instead use the values of those objects (I do this within a function).

HI,
Not sure I understand your question:
a <- 2
b <- 3
f1<- function(x) a+b*x
f1(2)
#[1] 8
f1(3)
#[1] 11
f<- function(x) 2+3*x
f(2)
#[1] 8
f(3)
#[1] 11
