[igraph] rglplot edge labels

[DANA MASTROVITO]

Hello,

I have created a graph in igraph using the graph.edgelist constructor.  I would like to plot the graph in 3 dimensions using rglplot.  I have successfully created the plot, however I have been unable to include edge labels in the plot.  When I include the

edge.label = labelnames

in the rglplot command I get the error:

Error in layout[,4] : subscript out of bounds

However, if I use the same labelnames variable and plot the graph in 2 dimensions there is no error. 

The labelnames variable is an array of 23 elements and the edge list variable is a matrix with dimension 23,2

Can you tell me what I am doing wrong.

Thank you.

Sincerely,

Dana
