[R] Selectively swapping labels between factors

[Michael Kubovy]

Dear R-helpers,

I'm trying to selectively swap labels between two factors, depending  
on an indicator variable i.

Can you point me to a solution, and perhaps how I could have found it?

labels(fact1) is a character vector of r row numbers
levels(fact1) is a character vector of the n < r unique levels
How do I then get the character vector of length r of the levels of  
fact1?
Once I have that, is there anything else I need to know about  
swapping labels between factors in a df?
