[R] Using two (...) in a function

[Benilton Carvalho]

isn't it simpler just to pass two vectors, say v1 and v2, in which one contains the object names and the other has the associated variances? (btw, "data" isn't a good function name)

myData <- function(v1, v2){
  Vec <- matrix(v1)
  varF <- v2
}

I may have misunderstood your question, but IMHO all you need is to guarantee that v1 and v2 are properly aligned.

Cheers,

b
