Subject: [R] Converting Factor to Vector

Hi all,

How can I convert factor like this:

> str(repo)
'data.frame':	1000 obs. of  1 variable:
 $ AAA: Factor w/ 1000 levels "AAT","AAC",..: 1 2 3 4 5 6 7 8 9 10 ...
> print(repo)
AAA
1  AAA
2  AAT
3  AAC
...

into to simple vector

> str(new_repo)
chr [1:100] "AAA" "AAT" "AAC" "AAG" "ATA" "ATT"...

> print(new_repo)
[1] "AAA" "AAT" "AAC" "AAG" "ATA" "ATT"...


I tried as.vector(), but it remains the same factor.
