R help - Apr 2008 - Associative array and How to store a set of objects ?

Hi,

Two questions:

A) Assuming OB is an object, how do I store 20 of OB in a vector or list ?
B) Does R has something similar associative array to Perl ? For example,
%our_friends = ('best', 'Don', 'good', 'Robert',
'worst', 'Joe');
$our_friends{'cool'} = "Karen";

Thanks
Stanley

replicate(20, OB, simplify=FALSE)

our.friends <- list(best="Don", good="Robert",
worst="Joe")
our.friends[["cool"]] <- "Karen"

PS. Concerning the second question, what about reading 'Introduction to
R'?
