Generate a lattice network

Syntax

nwlattice

[undirected
xwrap
ywrap
name(newnetname)
vars(newvarlist)
xvars
ntimes(int)]


`cols`	number of columns in lattice; first positional argument
`rows`	number of rows in lattice; default = 1 if omitted
`xwrap`	wrap horizontally
`ywrap`	wrap vertically
`undirected`	generate an undirected network; default = directed
`name`(newnetname)	name of the new network
`vars`(`newvarlist`)	new variables that are used for the network
`xvars`	generate Stata variables for the network
`ntimes(int)`	number of networks to be generated; default = 1
`noreplace`	reserved; currently a no-op - the create/replace collision guard on `name()` already applies regardless

Description

nwlattice generates a lattice network. Each node is connected to maximally four other nodes. With options xwrap and ywrap each node is connected to exactly four other nodes.

Examples

. nwclear
. nwlattice 4 4
. nwplot, label(_nodeid)

. nwclear
. nwlattice 4 4, xwrap ywrap
. nwplot, layout(grid) label(_nodeid)

Supported network types

Binary: yes (only). Directed: yes, via undirected (default is directed). Weighted: not applicable - no weights() option; generates a purely structural lattice. Signed: not applicable. Two-mode: not applicable - this generator always produces a one-mode network.

Stored results

nwlattice stores the following in r():
