Hi,
it's generally considered a bad practice but try this,
eval(parse(text=AA))

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)
This is the situation where it isn't considered bad practice. If someone
hands you a string with code in it, the only way to parse it is with
parse().
I think that Is there another way:
source(textConnection(AA))$value
closeAllConnections()
And if you look at the code for source(), you will see that it uses parse() and
eval().
