[R-sig-ME] Entry point for lme4a

[Koala]

I am trying to pinpoint the entry point into C++ functions for lme4a. This
function in external.cpp

RCPP_FUNCTION_6(NumericVector, merDeviance, S4 xp, NumericVector theta,
		NumericVector beta, NumericVector u0, int verb, int alg) {

seemed to be it, but it is being called multiple times. What is the
corresponding C function to lmer() call in R? I am trying to call lme4a from an
outside C++ function that I need to integrate.
