##### Count the isomorphic mappings between a graph and the subgraphs of another graph

Count the isomorphic mappings between a graph and the subgraphs of another graph

##### Usage
count_subgraph_isomorphisms(pattern, target, method = c("lad", "vf2"), ...)
##### Arguments
pattern
The smaller graph, it might be directed or undirected. Undirected graphs are treated as directed graphs with mutual edges.
target
The bigger graph, it might be directed or undirected. Undirected graphs are treated as directed graphs with mutual edges.
method
The method to use. Possible values: lad, vf2. See their details below.
...
Additional arguments, passed to the various methods.
##### Value

• Logical scalar, TRUE if the pattern is isomorphic to a (possibly induced) subgraph of target.
