graphvec 0.1.0

Initial CRAN submission.

New features

  • Added node_vec(), a graph vector of nodes with edges stored as attributes. Slicing induces a subgraph: edges that lose an endpoint are dropped, and remaining endpoints are remapped.
  • Added edge_vec(), a graph vector of edges with node data stored as attributes. Slicing selects edges directly, leaving nodes unaffected.
  • Added agg_vec(), an aggregation vector: a node_vec consisting of a parent value (the aggregated value) and its disaggregated children.
  • Added agg_df(), a table of agg_vec() columns, one row per level of aggregation, which can be reoriented into a graph.
  • Added nodes()/edges() generics to losslessly reorient a graph vector between node- and edge-indexed forms.
  • Added is_aggregated() to test whether an element is an aggregation of smaller data.
  • Added as.igraph() methods for node_vec, edge_vec, agg_vec, and agg_df, converting them to igraph::igraph() objects.
