Hi all,

   When renaming the levels of a factor f using levels(f)<-list(...), if the
list is longer than the original number of levels in f, the result is wrong.

Example:

> f <- factor(c("a","b"))

> levels(f) <- list(C="C", A="a", B="b")

Warning message: 
number of items to replace is not a multiple of replacement length 

> f
[1] C A
Levels:  C A 

The answer should be something like

[1] A B
Levels:  C A B

Thanks,
Hsiu-Khuern Tang.
