An eulerian path is a path in a graph which visits every edge exactly once. This function returns an eulerian path from a graph (if there is any). It works for both directed and undirected graphs.
1 
graph 
a 
start 

If start
is not NULL
, then eulerian returns a path starting from it. Otherwise, the start node is automatically selected.
A character vector representing an eulerian path/cycle in graph
. Each entry in the vector represents the name of a node in the graph.
