s0Make: Returns a data.table of structural 0 edges between 2 schools
In johninpdx/RSTools: Data Mangement Tools for RSiena and Other Network Packages

Description Usage Arguments Details Value Note

This is a 'helper' function which, along with s0Assemble, adds rows of structural zeros for individuals from different middle schools who, however, will be going to the same high school the next year...and are thus considered part of the same network, for analysis purposes.

1	s0Make(pVec1, pVec2)

`pVec1`	A vector of the RowIDs (note: not SIDs!) in middle school 1.
`pVec2`	A vector of the RowIDs in middle school 2.

To make connections between two wave 1 middle schools impossible, all you need to do is create an edge with value '10 (structural zero, in RSiena terminology) between each pair of individuals in the two schools. This function accomplishes that in a simple but efficient way. The function 's0Assemble' takes all the data.table objects created here and assembles them into one big table to return to the calling function.

A data.table in edgelist format; cols are RowID (chooser), RowID (chosen), bff (value of the relationship, an integer >= 0), and WID (wave ID #).

This function should not normally be used stand-alone. To see how it is used in context, consult the source code for 'getNetworkSet'. NOT EXPORTED
