R/igraph 0.4.2

June 7, 2007

This is another bugfix release, as there was a serious bug in the R package of the previous version: it could not read and write graphs to files in any format under MS Windows.

Some other bits added:

• circular Reingold-Tilford layout generator for trees
• corrected a bug, Pajek files are written properly under MS Windows now.
• arrow.size graphical edge parameter added in the R interface.
