igraph for R: R interface of the igraph library for graph theory and network analysis

• Remove igraph.eigen.default() and eigen_defaults, introduce internal eigen_defaults() as a function (#741).

• Remove broken nexus*() functions (#705), and srand() (#701).

• Update C core.

• ARPACK-based calculations are now interruptible.

• shortest_paths() and all_shortest_paths() no longer crash when an invalid from vertex is passed and weights are being used.

See diff for details.

• Use true vertex names for printing vertex sets. If a vertex set captures a relationship between vertices (e.g., the father component of bfs()), the vertex set is printed as a named vector (#754).

• Suggest restarting R session after fatal error (#745).

• as_long_data_frame() now correctly processes vertex attributes and works with graphs without vertex attributes (#748).

• as.hclust(hrg.fit(g)) works again (#721).

• The documentation is now available at https://igraph.org/ (#743).

• Reorganize function reference (#662).

• Replace graph() with make_graph() in examples (#738).

• Add docs for as.hclust.igraphHRG() (#733).

• Merged man page of hub_score() and authority_score() (#698).

• Refactor contributors listing (#647).

• Improve "family" titles (#679).

• Improve docs of ego/neighborhood functions.

• Improve transitivity() docs.

• Introduce cpp11 package to improve error handling in the long run (#720).

• Avoid longjmp for error handling and interrupts (#751).

• as.hclust.igraphHRG uses .Call() interface (#727).
