R help - May 2004 - obtaining the name of a named list

I have a list d, in which the names of each elements are single characters, 
and the actual elements are bit sequences representing those characters. If 
I type d[1], I get the name and the bit sequence. If I type d[[1]], I get 
only the bit sequence.

What I want is some way to be able to get the name of the element, 
preferably by specifying an index into the array.

e.g.

 > d
       A       B           C
"00000" "00001"  "0001"

I want some way of saying "give me the name for element number 2" and
it
should return B.


cheers,

Ned

d[1] returns a list of length 1, while d[[1]] returns only the element.

names(B)[2]

BTW: If all list elements are character of length 1, why are you not 
using a character vector instead?
