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
with_vertex_
modifier adds vertex attributes
to the newly created graphs.
See the examples and the various constructor modifiers below.
