netplot - Social Network Visualization


Syntax
        
        netplot var1 var2 [if] [in] [, options]


Description

netplot produces a graphical representation of a network stored as an extended 
> edgelist or arclist in  var1 and  var2. 


Options

    type(string) specifies the type of layout. Valid values are:

        circle: vertices are arranged on a circle

        mds: positions of vertices are calculated using multidimensional
            scaling. This is the default; omitting type() is equivalent to
            specifying type(mds).

    label specifies that vertices are to be labeled using their identifiers
        in var1 and var2

    arrows specifies that arrows rather than lines are drawn between
        vertices. Arrows run from the vertex in var1 to the vertex in var2.
        This option is useful for arclists that represent directed relations.

    iterations(#) specifies the maximum number of iterations in the
        multidimensional scaling procedure. The default is iterate(1000).


Remarks

An extended edglelist or arclist is a set of two variables representing
relations (i.e., edges (undirected) or arcs (undirected)) between entities
(vertices). Vertices are identified by the entries in the cells.  For example:

                 +----------+
                 |  v1   v2 |
                 |----------|
              1. |  1    2  |
              2. |  2    3  |
              3. |  4    .  |
                 +----------+

represents relations among four vertices. There are edges between 1 and 2 and
between 2 and 3. The fact that the value in v2 for vertex 4 is missing
indicates that vertex 4 is isolated.
