Is this basically what you want?

> xx <-list(aa = round(rnorm(30),2), f = function(a) a + b, a=x, b=x)
> xx
$aa
 [1]  1.34 -0.21 -0.18 -0.10  0.71 -0.07 -0.04 -0.68 -0.32  0.06 -0.59
 0.53 -1.52  0.31 -1.54 -0.30
[17] -0.53 -0.65 -0.06 -1.91  1.18 -1.66 -0.46 -1.12 -0.75  2.09  0.02
-1.29 -1.64  0.45

$f
function(a) a + b

$a
$a$a
[1] -0.06 -0.16 -1.47

$a$b
[1] -0.48  0.42  1.36


$b
$b$a
[1] -0.06 -0.16 -1.47

$b$b
[1] -0.48  0.42  1.36
