Cluster analysis


I would like to perform a cluster analysis on initially three variables
but possible extended to more if the initial analysis produces "good
results". Of the 3 variables, 1 is a continuous variable and the other
two are discrete variables and I'm using S-Plus and R to perform the
cluster analysis. I would like to construct either 2 or 3 clusters from
the analysis, but I'm not sure which method I should be using and the
metric. Can anyone one suggest the most appropriate method and metric
given the variables?

I would be very grateful for any asistence on this topic.


Best regards,

Eric
