Make a new graph


This is is generic function for creating graphs.





Parameters, see details below.


make_ is a generic function for creating graphs. For every graph constructor in igraph that has a make_ prefix, there is a corresponding function without the prefix: e.g. for make_ring there is also ring, etc.

The same is true for the random graph samplers, i.e. for each constructor with a sample_ prefix, there is a corresponding function without that prefix.

These shorter forms can be used together with make_. The advantage of this form is that the user can specify constructor modifiers which work with all constructors. E.g. the link{with_vertex_} modifier adds vertex attributes to the newly created graphs.

See the examples and the various constructor modifiers below.
