Thank you, I think I've indeed encountered the same issue (with 'R
--vanilla').  If I load package diveMove (which depends on stats4, in my
local development version) after lme4:

Now if diveMove is loaded before lme4 (with 'R --vanilla' again):

---<---------------cut here---------------start-------------->---
