# Strain Elevation Tension Spring Embedding

An R implementation for the Strain Elevation and
Tension embedding algorithm from Bourne (2020)
. The package embeds graphs and
networks using the Strain Elevation and Tension embedding (SETSe)
algorithm. SETSe represents the network as a physical system, where
edges are elastic, and nodes exert a force either up or down based on
node features. SETSe positions the nodes vertically such that the
tension in the edges of a node is equal and opposite to the force it
exerts for all nodes in the network. The resultant structure can then
be analysed by looking at the node elevation and the edge strain and
tension. This algorithm works on weighted and unweighted networks as
well as networks with or without explicit node features. Edge
elasticity can be created from existing edge weights or kept as a
constant.
