That does not sound like a clustering problem at all since you already know the
desired characteristics and are not trying to discover structure in your data.
Simply define a score as a suitably weighted sum of individual features, order
your passengers by that score, and pick the top few, or

You didn't look that hard...
Start with the Environmetrics Task View:

That might point you to the **vegan** pkg:

And that has a vignette on ordination which you might find useful.

How can I show the Dirichlet tile names (i.e. 1,2,3,,8) in the

There's no built-in way at the moment as far as I can tell.
One way to get the tiles to be labelled/numbered in the plot would be:
plot(dX)
mixtools package has mixture of Gaussian fitting, maybe that might help?

First this afternoon, I attempted to install R-3.2.0 from source on Windows

Ok. I figured that I had done something wrong with the source
installation. Now I just installed the binary.
Dear All,
I am a bit concerned about the memory consumption of randomForest in

This seems to e due to the fact that the option keep.forest=FALSE does

Does anybody know a workaround for that?
