[R-lang] p-values for mixed effects models with random slopes

[Alex Fine]

Hi,

I would imagine many or most of you are aware of the fact that the 
pvals.fnc function in the languageR package cannot currently estimate 
p-values for models that include random slopes.  Because we all need 
p-values, I'm guessing someone out there has developed a way of getting 
them from such models.  Has anyone implemented something that does this, 
or have any thoughts on this issue?

Thanks!
Alex
