Hi - since Rgraphviz was officially moved over to Bioconductor, this might be a misguided post, but it's worth a shot: I'm plotting a graph using Rgraphviz and in an attempt to force the edges to be behind the nodes (on a fairly complex graph), I set the "outputorder" graph attribute to "edgesfirst" (as is described in the graphviz docs here -> http://www.graphviz.org/doc/info/attrs.html). This field does also appear (although with a short and cryptic description) in the Rgraphviz package documentation. However I still will get some stray edges that traverse over the nodes. (And yes, I've set the "fillcolor" to a non-transparent color.) (Also, yes, I'm setting the rest of the graph/edge/node properties correctly as all of my other attribute settings are being honored by Rgraphviz.) The problem occurs with multiple devices including pdf(), png(), and X11(). Anyone else ever have edges on top of nodes and find "outputorder" ignores your request? -Murat [[alternative HTML version deleted]]
