I do not see that it has been "created" yet. You my have defined it
earlier in the 'list' expression, but as an object it is not available
yet. You might have to do something like uwing 'within'
> x <- list()
> x <- within(x, {
+ a = 1:10
+ b = 11:20
+ c = a + b
+ d = a * b})
> x
$d
[1] 11 24 39 56 75 96 119 144 171 200
$c
[1] 12 14 16 18 20 22 24 26 28 30
$b
[1] 11 12 13 14 15 16 17 18 19 20
$a
[1] 1 2 3 4 5 6 7 8 9 10
