|Date:||Wed, 14 Dec 2011 13:47:06 -0500|
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
