[R] Non-linear regression with latent variable

      If you have the "RSiteSearch" package installed, you can do the 

nrow(nll <- RSiteSearch.function("nonlinear regression with latent"))

      This just produced 8 hits for me.  If this doesn't solve your 
problem, you might  try other search terms.  If all those fail, you 
could write your own likelihood function and use the "maxLik" package. 

      Hope this helps.
