Cluster analysis: dissimilar results between R and SPSS
Hello everyone!
My data is composed of 277 individuals measured on 8 binary variables
(1=yes, 2=no).
I did two similar cluster analyses, one on SPSS 18.0 and one on R 2.9.2. The
objective is to have the means for each variable per retained cluster.
1) the R analysis ran as followed:
> call data
> dist=dist(data,method="euclidean")

cluster analysis: mean values for each variable and cluster
...luster=hclust(dist,method="ward")
cluster
plot(cluster)
rect.hclust(cluster, k=4, border="red")
I extracted 4 clusters from the data. My question is: is it possible to
produce a summary of every mean values for each variable of each of the 4
clusters?
Thanks a lot in advance,
Jeoffrey
