I don't think that it is a programming error, because I succeyyfully calculated subgraph isomirphism with the algorithm, but with smaller input graphs. So the algorithm seems to work. I already tried to set options(expressions=500000), but then I cause a protection stack overflow: error: protect(): protection stack overflow Is the problem that too many objects are stored in the stack? If yes, somebody knows how to solve this problem? thanks for your replies ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
