It sounds like you're looking for a library does frequent subgraph
mining across a graph dataset. I'm not sure what you mean by x-y plot
data, but if you can convert that into a graph, then look here:
http://www.borgelt.net/moss.html
It also has an implementation of the (famous) gSpan algorithm for
closed graph patterns (CloseGraph) in it as well.
It's not an R library though ... it's written in Java.
