Dear R users:
I am wondering how to ask for *fixed* number of distributions under parameterized Gaussian mixture model.

I know that em() and some related functions can predict the parameterized Gaussian mixture model. However, there seems no parameter to decide number of distributions to be mixed (if we known the value in advance).

That is, assume I know the (mixed)data is from 3 different distributions. The output, however, may indicate that number of distributions that form the data is 4. How can I assign number of distributions is 3 in advance?

Thanks a lot for your help.
