[Rd] Internal codes of the factor

[Gregor Gorjanc]

Hello!

I am writing some functions and I repeatedly acces internal factor
codes. I figured out that internal codes are 1:n where 1 represents 1st
level, 2 2nd level etc. This is not documented and I wonder if this is
on purpose and subject to change or would be a good idea to add this to
documentation for factor? I can prepair a pacth if this is accepted.
