Hi, igraph will give you the mappings via vertex ids. If you want to use symbolic vertex names, then attach a vertex attribute called 'name'. Then any vector of numeric vertex ids (v, from graph g) can be converted to vertex names via
V(g)$name[v] or the more readable equivalent get.vertex.attribute(g, "name", v) Best, Gabor On Tue, Jul 31, 2012 at 3:12 PM, HIMANSHU MITTAL <hm3...@gmail.com> wrote: > Hi all, > I want to find all the mappings of one graph in another graph, based on > their vertex labels > Is there any way to do this in igraph based on vertex labels. > (as far as i know Igraph allows the subgraph isomorphism based only on > vertex and edge colors) > > Eg: > graph 1: > x(1) x(2) > x(2) y(3) > y(4) x(1) > z(5) x(2) > > graph 2: > x(1) y(2) > > # the brackets contain the corresponding vertex ids > > i would like my output to contain the two mappings from graph 1 > i.e > x(2) y(3) & > x(1) y(4) > > Regards, > Himanshu Mittal > > [[alternative HTML version deleted]] > > ______________________________________________ > 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. -- Gabor Csardi <csa...@rmki.kfki.hu> MTA KFKI RMKI ______________________________________________ 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.
