How to load a specific variable from an RData file?

Create an environment, load the RData file into the environment, copy
over the items of interest, delete the environment.

e1 <- new.env()
load("gold.RData", e1)
ls()
[1] "e1"
ls(e1)
?[1] "a.mark" ? ? ? ? ? ? ? "aisleRange" ? ? ? ? ? "allSlots"

nfree <- get('nfree', e1)
ls() ?# now it is in the global workspace.
[1] "e1" ? ?"nfree"
How to remove the environment 'e1' after I get 'nfree'?

I'm wondering if there is any option available in load() such that I
