Hi Gabor, Thanks a lot for your help!
Those graph functions worked smoothly. I had to only change the flag allow.duplicates=TRUE in safer.merge function. I have another issue. Does the write.graph function support the xml or graphml format to write graphs? That way these graphs are easier to import in Cytoscape. Although .gml works well too but that's the only file format compatible to Cytoscape. Can you suggest some work around for this? Thanks a lot again.. -- View this message in context: http://r.789695.n4.nabble.com/Merging-graphs-with-common-nodes-tp3400017p3405258.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
