Comment:
The warning looks okay, but look at this hypergraph:
{{{
sage: H = Hypergraph([{1,2,3},{2,3,4},{3,4,5},{6,8},{7}])
sage: view(H)
}}}
I don't see an edge between 6 and 8. Also I get the following:
{{{
sage: H = Hypergraph([{1,2}])
sage: view(H)
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
<ipython-input-13-b92aa03e5aba> in <module>()
----> 1 view(H)
...
/home/travis/sage-5.10.rc1/local/lib/python2.7/site-
packages/sage/graphs/hypergraph.pyc in _latex_(self)
232 # "center", i.e. the vertex representing the set s
233 cx,cy = pos[s]
--> 234 s = map(lambda x:pos[x],s)
235 s = sorted(s, key = lambda (x,y) : arctan2(x-cx,y-cy))
236
TypeError: argument 2 to map() must support iteration
}}}
so something isn't quite working (similarly for any one set of vertices).
