[R] manipulating elements of lists

[Christoph Heibl]

I want to manipulate lists as described below:
Imagine these two lists:

 > list1
$WR7
[1] 1 2 3 4

$YH5YH6
[1] 3 4 5 6 7

$YH4
[1] 4 5

$UC4UC8
[1] 4 5 6 7 8 9

 > list2
           V1             	V2
1        WR7       	Averrhoa
2         ?     		Sarcotheca
3     	YH5YH6        	caesia
4        YH4      		arbuscula
5     UC4UC8          	rosea
6          ?     		acetosella

How can I exchange the names(list1) by the entries in the second  
column of list2,
if (a) length(list1) ­ length(list2) and (b) the elements of both  
lists are not in the same order? Is there a easy way to do this?

Thank you!
