Hello,

Say I have a dataset as followed:

Category     Value
b                1
b                2
a                7
a                1

Then, if I:

levels(Category)

It will return:
[a], [b]

But I want to keep the original order, i.e.:
[b], [a]

Is it possible to do it in R?

Thanks in advance!

Chris
