It turned out that I wrote the last post on “intergraph” package too hastily. After some feedback from CRAN maintainers and deliberation I decided to release the updated version of the “intergraph” package under the original name (so no new package “intergraph0″) with version number 1.2. This version relies on legacy “igraph” version 0.5, which is now called “igraph0″. Package “intergraph” 1.2 is now available on CRAN.
Meanwhile, I’m working on new version of “intergraph”, scheduled to be ver. 1.3, which will rely on new version 0.6 of “igraph”.
I am sorry for the mess.
