Diameter of a graph
The diameter of a graph is the length of the longest geodesic.
diameter(graph, directed = TRUE, unconnected = TRUE)
- The graph to analyize.
- Logical, whether directed or undirected paths are to be considered. This is ignored for undirected graphs.
- Logical, what to do if the graph is unconnected. If FALSE, the function will return the largest possible diameter which is the number of vertices. If TRUE, the diameters of the connected components will be calculated and the largest one will b
The diameter is calculated by using a breadth-first search like method.
- A numeric constant.
g <- graph.ring(10) g2 <- delete.edges(g, c(0,1,0,9)) diameter(g2, unconnected=TRUE) diameter(g2, unconnected=FALSE)
Looks like there are no examples yet.
