R help - Mar 2006 - choosing a particular object

Hello all,

I'd like to create a function which would do some analysis on a particular 
object, which should be specified in advance. Something like:
> ls()
[1] "aa" "bb" "cc"

Object <- "bb"
var.name <- "q2"
testfunction <- function(obj.name, var.name) {
  temp <- give.me.the.object.called(Object)
  table(temp[, var.name])
}

This should perfom the same thing as:
table(bb$q2)

Is this possible?
TIA,
Adrian

Try

 test.fn <- function(obj.name, var.name="q2"){

  stopifnot( is.character(obj.name) & is.character(var.name) )
  x <- subset( get(obj), select=var.name )
  table(x)
 }
