0.10 functions that should be exposed

[szhorvat]

Priority 0

This is a list of functions that are new in 0.10 and should probably be exposed in the very first R/igraph release based on 0.10. Should be easy through auto-generation. The igraph_ part is omitted from function names.

• is_forest and is_acyclic
• has_mutual -> any_mutual
• invalidate_cache — we need this for debugging
• ... ?

Priority 1

These would be nice to expose soon though perhaps not in the first release. Several of these were requested by users. Auto-generation is not always possible.

• hub_and_authority_scores to replace separate hub and authority score calculation
• get_k_shortest_paths Add k_shortest_paths #972
• graph_center
• ... ?

Add support for extra features to existing functions. These are often a separate function in C, but should be integrated into the same function in R.

• radius_dijkstra and eccentricity_dijkstra (i.e. weight support for both, Could the functions eccentricity() and radius() be implemented for weighted graphs? #893)
• distances_cutoff (cutoff support)
• ... ?

Generators (probably all of these can be auto-generated):

• circulant
• turan
• wheel
• full_multipartite
• regular_tree
• symmetric_tree
• triangular_lattice
• hexagonal_lattice
• generalized_petersen
• ... ?
