I have two factors l1, l2, and I'd like to merge them.

(Remark:       The factors can not be converted to charaters)

Function c() does not give me the result I want:


> l1 = factor(c('aaaa', 'bbbb'))
> l2 = factor(c('ccc', 'dd'))
> lMerge = factor(c(l1, l2))
> lMerge
[1] 1 2 1 2
Levels: 1 2
>
I'd like to merge l1 and l2 and to get lMerge 
----------------------------------------------

[1] aaaa bbbb ccc dd
Levels: aaaa bbbb ccc dd

instead of 
----------

[1] 1 2 1 2
Levels: 1 2
>

How should I do that without converting the factors back to strings.
