[R] Fwd: the properties of a DATA to run DBSCAN in R

[Maryam Heidari]

hello everybody,

I have been trying to run "dbscan" algorithm on my data, my data round
40000 records which each of them has 3 attributes + plus the ID for each
record.
the interesting thing is that when I run the "dbscan just on 3 attributes"
R gives me an ERROR regarding "stackoverflow" but when I run it including
the 4 attributes it runs with out any problem.
so is the problem with my data?!

this is statistics about my data
   att1                           att2                                att3
