Hi guys,
I ran into a problem of not being able to create unique labels when creating a
factor. Consider an example below:
hb <- factor(c(1,1,1,2,2,2,3,3,3), levels=c(1,2,3),labels=c(1,1,2))
> hb
[1] 1 1 1 1 1 1 2 2 2
Levels: 1 1 2
> unique(hb)
[1] 1 1 2
Levels: 1 1 2
How come there are three unique levels, I thought this would only create one
unique level?
> unique(as.ordered(hb))
[1] 1 2
Levels: 1 < 1 < 2
Is as.ordered the only solution?
Thanks in advance,
Greg
