Very simple as explained in the help files:
> X <- 1:5
> X
[1] 1 2 3 4 5
> add.value.labels(X,letters[1:5])
[1] 1 2 3 4 5
attr(,"value.labels")
a b c d e
1 2 3 4 5> X
[1] 1 2 3 4 5
X didn't change.
> X <- add.value.labels(X,letters[1:5])
> X
[1] 1 2 3 4 5
attr(,"value.labels")
a b c d e
1 2 3 4 5>
X changed. Mind you, those value labels are only read by functions
that use it. functions like names(), colnames(), rownames() and the
likes won't use those labels.
If you really want to use a kind of labels that works in almost every
situation, just use factors.
