This is a generic function for creating graphs.
Details
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.

Examples
r <- make_(ring(10))
l <- make_(lattice(c(3, 3, 3)))
r2 <- make_(ring(10), with_vertex_(color = "red", name = LETTERS[1:10]))
l2 <- make_(lattice(c(3, 3, 3)), with_edge_(weight = 2))
ran <- sample_(degseq(c(3, 3, 3, 3, 3, 3), method = "configuration"), simplified())
degree(ran)
#> [1] 3 3 3 3 3 3
is_simple(ran)
#> [1] TRUE
