Hi everybody,
this is probably a silly question, but I can't find a way to recognize
the names that are passed
to variables in ellipsis.
For example, say I have a "core" function that receives some extra
parameters through ...
e.g.
f <- function(...) {
params <- c(...)
#dothehardworkhere using "names(params)"
}
The usual method is to use list(...) which retains the names, not c(...).
and then I want to create a function g where some of the parameters
are set like:
g <- function(x,y) f(x,y)
I figure I probably have to use to substitute in f, but it is not
clear to me how.
Definitely what I need to achieve is that when I call:
g(1,2) then in f params is the vector c(x=1,y=2);
similarly I want to be able to call g(y=2, x=1)
and have params = c(x=1,y=2) in f.
Can you please help me understanding how to do this?
Can't you just call g(...)? I don't understand what the problem is.

Thanks a lot for your help!
