remap_ids
(w, old2new, id_order=[], **kwargs)[source]¶Remaps the IDs in a spatial weights object.
Spatial weights object
Dictionary where the keys are the IDs in w (i.e. “old IDs”) and the values are the IDs to replace them (i.e. “new IDs”)
An ordered list of new IDs, which defines the order of observations when iterating over W. If not set then the id_order in w will be used.
optional arguments for pysal.weights.W
Spatial weights object with new IDs
Examples
>>> from libpysal.weights import lat2W
>>> w = lat2W(3,2)
>>> w.id_order
[0, 1, 2, 3, 4, 5]
>>> w.neighbors[0]
[2, 1]
>>> old_to_new = {0:'a', 1:'b', 2:'c', 3:'d', 4:'e', 5:'f'}
>>> w_new = remap_ids(w, old_to_new)
>>> w_new.id_order
['a', 'b', 'c', 'd', 'e', 'f']
>>> w_new.neighbors['a']
['c', 'b']
