R help - Apr 2011 - Estimates at each iteration

Dear Sir\ Madam
 I am trying to maximise a complicated loglikelihood function  via EM algorithm 
which consists of two step "E-step and M-step"and in this case I need
to
maximize the expected of like lihood function " which I get from E-
step" and
take those estimates of parameter to update the E-step and repate these till 
convargence has been met. So I need to know if I control the number of iterlim 
in maxLik or optim Package by puting this number equals to one to maximize 
M-step and getting  just the estimates of parameter for one iteration and hence 
use them to update the E-step and again maximaize M-step by using maxLik or 
optim by contoling the number of limiter and putting the number equals to 1 
is it true and acceptance? I mean if I do this my results can be 
reasonable?. please I am waiting your response.

I'm assuming that English is not your first language. In light of that, I 
would suggest that you post your question in a language that we both 
speak: R. Please include:

1) E-step and M-step functions.
2) The proposed optim/maxLik call.

Mostly because (at least optim) does not have a parameter called 
"limiter".
