Re: clustering using NCL

I have using R to perform cluster analysis and NCL to manipulate the
results.

Please, take a look at

http://fs6.depauw.edu:50080/~harvey/Chem%20351/PDF%20Files/Handouts/RDocs/Using%20R%20for%20Cluster%20Analysis.pdf

for a quick tutorial about using R for cluster analysis.

Best regards,

Mateus
