Re: [igraph] Vertex colors in tkplot

[Chacko, George (NIH/CSR) [E]]

Hello:

 

I am trying to assign vertex colors from a lookup table when visualizing graph.adjacency output in tkplot. This works using plot which is unfortunately not interactive.

 

Ø  plot(g1, vertex.label=row.names(df1),vertex.color=(IRG_ColorList[,2]),layout=layout.fruchterman.reingold)

 

but not with tkplot

 

Ø  tkplot(g1, vertex.label=row.names(df1),vertex.color=(IRG_ColorList[,2])

 

Error in structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), class = "tclObj") :

  [tcl] unknown color name "1".

 

Is this a known problem for which there is a workaround? I’d be grateful for any help. Thanks George Chacko
