Dear all,
Unaware of any method for dealing with multigraphs (in my case a family of
graphs "g" indexed by time), I handle these by creating a list, indexed by
the time period, say "Mygraphs", where Mygraphs[["2014-01-01"]] returns
graph g as it was in 2014-01-01.
I face the need to extract a combination of attributes from the series (in
the example below the vertex's "id" and "betweeness", ordered by the index
of Mygraphs), I do so for example as follows:
sapply(
Mygraphs,
function(g,id="identifierXX",attr="betweeness") {
get.vertex.attribute(induced.subgraph(g, which(V(g)$name==id)),attr)
}
)
I cannot help to think that the use of induced.subgraph could be obviated
by specifying the 2 dimensions (id and attr) at once in the extraction, but
I how would I restrict get.vertex.attribute to only return the value for
vertex "identifierXX" only?
Any guidance would be appreciated.
Kindly,
Bob Pap
