get.node.attr

The <code>get.node.attr</code> function returns the vector of nodal covariates for
the given network and specified attribute if the attribute exists -
execution will halt if the attribute is not correctly given as a single
string or is not found in the vertex attribute list; optionally
<code>get.node.attr</code> will also check that return vector is numeric, halting
execution if not. The purpose is to validate assumptions before passing
attribute data into an ergm term.

An integrated set of tools to analyze and simulate networks based on exponential-family random graph models (ERGMs). 'ergm' is a part of the Statnet suite of packages for network analysis. See Hunter, Handcock, Butts, Goodreau, and Morris (2008) <doi:10.18637/jss.v024.i03> and Krivitsky, Hunter, Morris, and Klumb (2023) <doi:10.18637/jss.v105.i06>.
