R help - Oct 2009 - Creating object referant from argument name

Hi all. I'd like to define an object within a function based on an argument
to that function.
Specifically, I've got:

do.something<-function(input){
id<-substring(input,3,3)
j<-list1
if(id==2)j<-list2
if(id==3)j<-list3
if(id==4)j<-list4
...}

Instead of all these if() arguments, I was hoping to use something like:
j<-paste("list",substring(input,3,3),sep="")
but this just assigns j the value of "listx" of _character_ mode,
instead of
the actual object 'listx'.
Is there any way to get around this?
Thanks.
