R help - Aug 2005 - Fitting mixture model

I would like to fit a gaussian mixture model to a vector with about 50,000
points.  I have tried using Mclust to do so, but 50,000 points requires more
memory than I have (and I am running with 4Gb).  Any other suggestions for
how to do so?  Oh, I don't know the number of components, but the number
will likely be less than 5 or 6.

Thanks,
Sean

I don't know if and how exactly it works for your data but package flexmix
should also allow to fit Gaussian mixtures.
