Embed R, and provide a function to user scripts

Essentially I'd like to load the C function into ?the load table
After that, I can create an R function
rboo=function(x) .Call("boo",x)

then user script cann call rboo

Hope that clarifies things.
Thanks in advance

Hello,
I'm not sure how to go about this. Suppose I have a function

SEXP boo(SEXP x){
//do something
}

Also, I have an executable which embeds R in itself. I would like to
provide a R function to user code to call that calls 'boo' e.g

##user supplied expression that is given to me

x<-1
boo(x)

One way is to create a library with function boo that performs .Call to
boo, but is there a way that I can do something like

ainstall("rboo", boo)

and calls to rboo in the language will be sent to 'boo' ?

Thank you
