Odp: Problem with retrieving updated variables after attach()

Well, I knew that attach() only creates a copy of the variables in the search path. What I wanted to ask was how to *retrieve* that copy...
mat
id age 1 NA NA 2 NA NA 3 NA NA 4 NA NA 5 NA NA
attach(mat)
id <<- sample(100,5) age <<- rnorm(5,mean=30)
How can I make a new data frame out of the id and age that were changed above?
data.frame(id, age) # from the copy data.frame(mat$id, mat$age) # from the originals why do you need to overwrite the copy? vQ
