The getComponents function returns all the connected
components of a graph.
Usage
getComponents(nodes, arcs)
Arguments
nodes
vector containing the nodes of the graph,
identified by a number that goes from $1$ to the
order of the graph.
arcs
matrix with the list of arcs of the graph.
Each row represents one arc. The first two columns
contain the two endpoints of each arc and the third
column contains their weights.
Value
getComponents returns a list with all the components
and the nodes of each one ($components) and a matrix
with all the arcs of the graph and its component
($components.arcs).
