[TODO] Data laboratory: reversing the directions of edges?

Post by seinecle » 08 Sep 2010 11:01

Hi,

I found it a frequent need to be able to quickly change the direction of my edges (that is, inverting the direction of all edges: if I have a graph made of a->b and b->c, it would become b->a and c->b. It basically consists in transposing the matrix of nodes.

Will it be possible to achieve this easily with the new data laboratory?

[this feature is useful when computing betweenness and many other things, as it does not give the same result for a transposed matrix. See UCINET]

Hi, this is a good idea that could be useful as a data laboratory action.
I will think how to implement it, some edges could not be possible to be reversed in some cases.

Sorry, this is not implemented (it's still considered for implementation) since it wasn't critical or very needed.
