You said you were getting expected results with:

qqnorm(modelincrF)

I was pointing out that the R methods dispatching was actually  
applying the function "qqnorm.lme" function to that model object and  
that all of the parameter options should be available, in particular  
the line drawing options that can be specified for parameter abline. I  
was _not_ suggesting that you call the function in the manner that you  
did. I _was_ suggesting that you read the correct help page.  Try the  
examples in the help page for qqnorm.lme  and notice how the examples  
call it.

?methods

It's:
?qqnorm.lme  # just one "?"
