This function defines and initializes the fuzzynodematch ERGM term that allows for generalized homophily.
InitErgmTerm.fuzzynodematch(nw, arglist, ...)An object of class network.
A list of arguments as specified in the ergm.userterms
package framework.
Additional data passed into the function as specified in the
ergm.userterms package framework.
This ERGM user term was written to allow for generalized homophily.The
attr term argument should specify a character vertex attribute
encoding the "venues" associated to each node. The split argument
should specify a string that separates different "venues" in the attribute
value for each node, as handled by strsplit with fixed = TRUE.
For example, if split is "|" (the default), and the attribute
value for a given node is "a12|b476", then the associated venues for
this node are "a12" and "b476". The empty string "" is
interpreted as "no venues".
If the binary term argument is FALSE (the default), the change
statistic for an on-toggle is the number of unique venues associated to both
nodes (informally speaking, this could be described as the number of venues
on which the two nodes "match"); if binary is TRUE, the change
statistic for an on-toggle is 1 if any venue is associated to both
nodes, and 0 otherwise.
