About igraph releases and other things
R-igraph 1.3.2, the second bugfix release of the 1.3 series is now released – and it looks like we forgot to post an announcement about 1.3.1, so in the rest of this post we summarnize the changes in versions 1.3.1 and 1.3.2 as well.
As always, we tried to do our best not to cause breaking changes for users of igraph from R, but in case we have made unintentional mistakes, please report issues in the Github issue tracker.
The C core is updated to 0.9.9, fixing a range of bugs.
communitiesobjects is now reported correctly.
layout_with_kk()would fail to produce reasonable results with the default initial coordinates. This has been corrected, however, this function no longer produces precisely the same output for a given graph as before. To restore the previous behaviour, use
layout_with_kk(g, coord=layout_in_circle(g))in 2D or
layout_with_kk(g, dim=3, coord=layout_on_sphere(g))in 3D.
v[x, na_ok=T]now correctly handles the
na_okargument in all cases; previous versions ignored it when
xwas a single number.
graph_from_adjacency_matrix()now works with sparse matrices even if the cell values in the sparse matrix are unspecified.
cluster_walktrap()no longer accepts invalid weight vectors.
cluster_walktrap()no longer returns a modularity vector of invalid length for disconnected graphs. This also fixes some rare failures of this function on weighted disconnected graphs.
edge_attr()does not ignore its
index=...argument any more.
canonical_permutation()now allow all possible values supported by the C core in the
shargument. Earlier versions supported only
vertex.frame.widthplotting parameter now allows zero and negative values; these will simply remove the outline of the corresponding vertex.
shargument of the BLISS isomorphism algorithm in
isomorphic()was fixed; earlier versions incorrectly referred to
dominator_tree()now conforms to its documentation with respect to the
domcomponent of the result: it contains the indices of the dominator vertices for each vertex and
-1for the root of the dominator tree.
page_rank()have been removed from the documentation, as this method is no longer available.
