[R] Problem to predict new data with mclust

[Sarah Goslee]

Hi,

It's unlikely that anyone will be able to see your problem without a
reproducible example.

Are you using the mclust package? That would be the first thing we need to know.

Then, have you worked through the examples in ?predict.Mclust, and do
you understand them?

Then, what do your data look like? str() and such are useful, but the
best option is to use dput() to create a reproducible subset, or to
reproduce your problem using one of the built-in datasets in R, as is
done in the above documentation examples.
