The loongraph class provides a simple alternative to the graph class to create common graphs that are useful for use as navigation graphs.
loongraph(nodes, from = character(0), to = character(0), isDirected = FALSE)
graph object of class loongraph
a character vector with node names, each element defines a node hence the elements need to be unique
a character vector with node names, each element defines an edge
a character vector with node names, each element defines an edge
boolean scalar, defines whether from and to define directed edges
loongraph objects can be converted to graph objects (i.e. objects of class graph which is defined in the graph package) with the as.graph function.
