`nwkeep`

Keep networks or nodes

Syntax

nwkeep 
[netname]

[,
clean]


`clean`	Drop node observations

Keeps a network or a list of networks. The command is the network version of keep and mirrors nwdrop.

It can also be used together with if or in. In this case, the command operates on the node-level and keeps only certain nodes of a network.

Load two networks and keep only one of them by name:

. nwclear
. nwrandom 5, prob(.4) name(net1)
. nwrandom 5, prob(.4) name(net2)
. nwkeep net2
. nwset

Keep only certain nodes of a network, using if:

. nwclear
. nwrandom 6, prob(.4) name(net3)
. nwkeep net3 if _n <= 3
. nwsummarize net3
