[R] function to carry out Bootstrap LRT with poLCA results

[Alain D.]

Dear List, 

I would like to determine the optimal number of latent classes (polytomous data)
using Bootstrap LRT. poLCA does not provide such a possibility and I am not
enough into programming to modify the code. Is there any other way to do this,
e.g. use a poLCA object with some other package?

Thank you for help.

Best wishes

Alain
