Rgraphviz - issue with edge label when using multiple edges between two nodes

Dear All

I am using Rgraphviz to plot graphs in support to a research in the machine learning field. In the current stage we are working with chain of events graph generation, and these graphs usually have multiple edges between 2 nodes, and each edge has its own label and occurrence probability (rank).

I have searched the Rgraphviz documentation and internet forums without success. All packages were updated.

Issue:

When trying to plot more than one edge between two nodes with  distinct labels, the Rgraphviz uses only the first informed label to all these edges, ignoring the following labels. You can replicate this using the simple example that follows:

g <- new( "graphNEL", nodes= c("a","b"), edgemode="directed", edgeL= list( a = c("b", "b","b" ), b=c()) )
plot( g, main="test", edgeAttrs= list( label = c("a~b"="Y-label", "a~b"="Z-label", "a~b"="")), attrs=list(graph=list(rankdir="LR")) )

 

Current environment (another researcher observed the same issue under a windows 7 environment)  - sessionInfo() output:

R version 3.1.1 (2014-07-10)
Platform: x86_64-suse-linux-gnu (64-bit)

[11] LC_MEASUREMENT=pt_BR.UTF-8    LC_IDENTIFICATION=pt_BR.UTF-8

attached base packages:
[1] grid      stats     graphics  grDevices utils     datasets  methods  
[8] base     

other attached packages:
[1] Rgraphviz_2.10.0 graph_1.44.1     rkward_0.6.1    

loaded via a namespace (and not attached):
[1] BiocGenerics_0.12.1 parallel_3.1.1      stats4_3.1.1       
[4] tools_3.1.1   

 

 

Any advise will be highly appreciated

This sounds like a bug. Could you add an issue to the Github repos, so I don't forget? I have a number of things I need to address with Rgraphviz, so I am envisioning a coding session (aka bug fixes and enhancements) really soon.
