Hello.

I have a general question regarding to clustering of association rules.
According to http://cran.r-project.org/web/packages/arules/vignettes/arules.pdf
"4.7 Distance based clustering transactions and associations" there is possibility for creating clusters of association rules.
I do not understand, how I have to interpret clusters of rules.

Let us have next association rules and clusters (see table).
My final goal is to have clusters of items.
Does it mean that items 11180, 10378, 52848, 11451, ..., 50417 are all in cluster "1" ?
What is the point of clustering of association rules, how do I have to use them for clustering of items which are present in rules?
