igraph (version 1.1.1)

make_: Make a new graph

Description

This is is generic function for creating graphs.

Usage

make_(...)

Arguments

...

Parameters, see details below.

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 link{with_vertex_} modifier adds vertex attributes to the newly created graphs.

See the examples and the various constructor modifiers below.

Examples

# NOT RUN {
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 = "simple"), simplified())
degree(ran)
is_simple(ran)
# }
