[R] PAM Clustering Ignores Cluster Number Parameter

[Dario Strbenac]

I am using PAM with k = 10 clusters, but I only get one cluster ID for all my observations. I couldn't find any discussion about this in the help file, or mailing lists.

Is there a reasonable explanation for this result ?

cIDs <- pam(all, 10, cluster.only = TRUE, do.swap = FALSE)
> table(cIDs)
cIDs
    0 
16671

The matrix of observations can be found at : http://129.94.136.7/file_dump/dario/all.obj

I'm using R version 2.13.0 (2011-04-13) on Platform: x86_64-unknown-linux-gnu (64-bit) and have cluster_1.13.3.
