With regard to R indexing on the objects have you thought about using
the __getitem__ method of an attribute.
E.g. python indexing m[:,1], r indexing m.r[:,2]
class RIndex(object):
def __init__(self, parent):
self.parent = parent
def __getitem__(self, index):
return self.parent.subset(index)
def __setitem__(self, index, value):
#pass
class RObject:
def __init__(self, robj):
self.r = RIndex(self)
