Adding a function in R for use without loading it

So I have code for a custom function in R, e.g. simply:

f <- function(x) return(x)

What I want to do is be able to call this function f as if it came with default R. That is, I don't want to have to source() the file containing the code to be able to use the function. Is there a way to accomplish this?

What you are looking to do is documented extensively under ?Startup. Basically, you need to customize your Rprofile.site or .Rprofile to include the functions that you want available on startup. A simple guide can be found at the Quick-R site.

One thing to note: if you are commonly sharing code with others, you do need to remember what you've changed in your startup options and be sure that the relevant functions are also shared.
