The function 'growth' (in the lavaan package) can be used for (standard) 
growth modeling. Good material about growth modeling (using Mplus) can 
be found here:

Next, you can read how to do growth modeling with lavaan by reading 
section 7 in the lavaan intro, which you can download from the 
documentation section on the lavaan website (http://lavaan.org).
