Read Highland Tribes

Description

A network of political alliances and enmities among the 16 Gahuku-Gama sub-tribes of Eastern Central Highlands of New Guinea, documented by Read (1954).

Format

An undirected network object with no loops, having the following attributes:

%v% "vertex.names"

Character attribute with names of tribes.

%e% "pos"

Logical attribute indicating an alliance relationship.

%e% "neg"

Logical attribute indicating a hostile relationship ("rova").

%e% "sign"

Numeric attribute coding -1 for enmity, 0 for no relationship, and 1 for alliance.

%e% "sign.012"

Numeric attribute coding 0 for enmity, 1 for no relationship, and 2 for alliance.

Because of limitations of network objects, the object itself is a complete graph, and is thus meaningless if used directly or plotted.

Details

This network shows 3 clusters.

# Only model positive ties:

# Edge color must be set manually, for green ties to represent alliance
# and for red ties to represent enmity.
