[R] How to take out the content of character string

[jq81]

My question is represented by the following example.

For example, I have a character string a, which is defined as

AA="list(x=1, y=2)"

I want to take out the content of AA by using some function, so that I can
obtain the following expression automatically.

list(x=1, y=2)

Does anyone know how to do it? Thanks a lot,
