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. Duncan Murdoch
Thanks a lot for your help!
