Ni! avg_neighbour_corr considers as neighbours of v the targets of edges for which v is source.
The documentation on the website already states this correlation in terms of 'source' and 'target', and in any case it is pretty straightforward to check what it is doing... but if you want to dig it you'll end up looking at a c++ class called GetNeighboursPairs. Generally, you should usually expect directedness to be respected, and either use g.set_directed() or a GraphView if you want to treat the graph as undirected for some measure. If you need to correlate a directed measure while treating the graph as undirected, for example for avg_neighbour_corr to correlate in-degrees disregarding edge direction, create a property map to record the directed measure, then turn the graph into undirected and run the correlation for the recorded property.
