# Clusplot and variability

I'm testing the clara algorithm with a dataset, but as we can see in the figure:

I got the message "These two components explain 1.06% of the point variability"

What can I conclude about this? The image splits with a good accuraccy

      a   b
1 150   0
2   0  50


But that message makes me confuse if I have some problem.

library(cluster)
cl <- clara(a[,-which(colnames(a) == "STATUS")],3)
table(cl$clustering,a$STATUS)
plot(cl)


Also the graphic from the silhouette is empty. With an average of 0 in the silhouette.
