[R] List of varying length suitable for use as dimnames

[jim holtman]

It is easy enough to create the list, the real question is what do you
want in it ( provide commented, minimal, self-contained, reproducible
code).  Here is the list:

> x <- vector('list', 10)
> names(x) <- paste("SS", 1:10, sep='')
> x
$SS1
NULL

$SS2
NULL

$SS3
NULL

$SS4
NULL

$SS5
NULL

$SS6
NULL

$SS7
NULL

$SS8
NULL

$SS9
NULL

$SS10
NULL
