em algorithm

Hi to everyone! I am trying to do the expectation maximization algorithm for
 a bivariate distribution that has a difficult expression and I can't compute
 the mle. The only examples I found by now are either for univariate (from
 the exponential family) distributions or a mixed normal. Is there anyone
 that can explain it to me with an example at a bivariate case? Sorry for my
 english, is not my native language and I am new to R. Thank you all in
 advance!
