I'm using the Rgraphviz package (Rgraphviz_2.10.0) to plot a network in R and would like to have multiple colors per node. Basically, I would like to split the nodes into stripes and have a different color for each stripe. 

I looked into using the "striped" node style but have troubles getting it to work. In the graphviz documentation it says that multiple colors can be passed to a node by using a colorList, but it's not clear to me if colorLists are supported in Rgraphviz and how the correct syntax would look like. 

Any help or suggestions would be appreciated!
