This is my usual workflow, but should work with any graphNEL object. The code looks complex because my node labels sometimes have new line characters "\n". The function basically takes the fontscale (12) and scales fontsizes down to take into the longest label. Hope this helps. g <- new("graphNEL", nodes = myNodes, edgeL = myEdges, edgemode="directed") names(labels) = labels = nodes(g) fixedsize = rep(FALSE, times=length(nodes(g)) fontscale = 12 fontsize = fontscale * max(nchar(unlist(strsplit(labels,"\n", fixed=TRUE)))) / sapply(labels, function(x) { max(nchar(unlist(strsplit(x,"\n", fixed=TRUE)))) }) fontsize[is.infinite(fontsize)] = fontscale names(fill) = names(shape) = names(fontsize) = names(width) = names(height) = nodes(g) Note: fill, shape, width & height are all vectors which I set to get custom node shapes, sizes, and fill color. g <- layoutGraph(g, layoutType = "dot") nodeRenderInfo(g) = list(label = labels, shape = shape, fontsize = fontsize, height = height, lWidth = width/2, rWidth = width/2, fill = fill) g <- renderGraph(g) Cheers, Fraser -----Original Message----- From: bioconductor-bounces@stat.math.ethz.ch [mailto:bioconductor-bounces at stat.math.ethz.ch] On Behalf Of Quin Wills Sent: Thursday, July 08, 2010 8:44 PM To: bioconductor at stat.math.ethz.ch Subject: Re: [BioC] Rgraphviz: flexible node sizes Anybody?
