Dear R - users/Helpers

 I am dealing with bivariate Normal data with missing values. Further I am trying to implement Expectation-Maximization (EM) algorithm to  resolve the missing data problem.
 Now one of the requirements is use the Log likehood function i.e -2Log so as to find a reliable convergence....

       My question is there any R  built function for the same or do i have to use the packages contributed by other R Developers.

Regards
Kunal
