minnesota {gasper} | R Documentation |
A dataset representing the Minnesota road network along with two associated synthetic signals.
minnesota
A list with 5 elements:
xy
A matrix indicating the spatial location of each node.
sA
A sparse matrix representation of the road network's adjacency matrix.
f1
Synthetic signal generated with parameters \eta = 0.01
and k = 2
.
f2
Synthetic signal generated with parameters \eta = 0.001
and k = 4
.
labels
A character vector with labels that represent various points of entry, border crossings, and notable cities within Minnesota, with some nodes possibly lacking specific location identifiers.
The Minnesota roads graph represents a planar structure consisting of 2642 vertices and 6606 edges.
The signals come from the referenced paper generated using randsignal
with parameters \eta=0.01, k=2
and \eta=0.001,k=4
