Imagine you have an object foo that you saved as saved.file.rda as follows:

foo <- 'a'
save(foo, file='saved.file.rda')

Suppose you load saved.file.rda into an environment with multiple objects but forgot the name of the object that is in saved.file.rda. Is there a way in R to determine that name?

You can do it the following way, which seems a little clunky:

bar <- load('saved.file.rda')
eval(parse(text=bar)) # this will pull up the object that was in saved.file.rda

However, is there a better way of doing this?
