Undocumented argument na.last in factor()

Gregor Gorjanc-2
Hello!

I just noticed that argument na.last in factor() is not documented. Did
I miss something or ...? I just wonder how base package passes then R
CMD check. I checked also in source man page in R-devel.

I wondered too -- for a few moments only -- after reading your
message...

*BUT*  na.last  is *not* an argument to factor()!

Look more carefully  at   str(factor)  or args(factor)
(or the help page) !

Argh, yes you are right. Argument na.last is for sort for levels. I
apologize for this.
