I am using 'igraph' package to make some graphs of 'gene-gene interaction'.
I can get a data.frame which has three columns. gene1 gene2 pvalue AGT MLR 1.2e-04 MLR 11BHSD1 1.71e-05 IFG2 11BHSD2 2.2e-07 . . . . . . . . . AGTR1 NPPA 3.2e-2 I have several questions: 1) How can I make a plot in which the width of the edges can represent the significance of the epistasis p values? I am thinking about getting another column which is the -log(pvalue), so the larger the value is the more significant the p value is. 2) After I get the graph, how can I modify the image. Because all the nodes in the image are numbers (0,1,.....,100), how can I add the gene name to each node in the image? -- View this message in context: http://r.789695.n4.nabble.com/Questions-about-igraph-package-tp3412734p3412734.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.
