Hi!

My name is Raphael Saldanha, I'm a student in Brazil.

I'm using R by the first time now (and maybe my english too! hehehe), it's
really a very good program for spatial data analysis. But I have some
questions:

1. How can I discard some variables using princomp with a dataframe?
2. Watch is the best way to use the components (from princomp) as data in a
cluster analysis (i.e. kmeans)?
2. How can I obtain the cluster for each observation using kmeans?

I think it's very simple doubts, please help me!

Thanks from Brazil!

Raphael
