Re: [igraph] bipartite.projection and weighted graphs

[Tamás Nepusz]

the most important being that igraph 0.6 will use 1-based indexing instead of 0-based indexing

Please explain.

This applies only for the R interface, not for the C core or the Python interface. In R, vectors are commonly indexed from 1 and not 0, so igraph's current zero-based indexing was/is confusing for most users.
