Consider:
f1 <- function(...){
one <- list(...)[['a']]
two <- ...elt(match('a', ...names()))
c(one, two)
}
## Here "..." is an argument list with "a" somewhere in it, but in an
unknown position.
> f1(b=5, a = 2, c=7)
[1] 2 2
Which is better for extracting a specific named argument, one<- or
two<- ? Or a third alternative that is better than both?
Comments and critiques welcome.
Cheers,
Bert
