Change edge thickness with tkplot (Igraph, R) -

-

i wondering if there way change edge thickness when using tkplot()

i know can right clicking edge , changing manually, able call attribute use edge. similar when using normal plot function in igraph can edge.width=e(g)$weight

also, there way save tkplot png without use of other packages? thanks!

yes, can change edge width, works same way plot().

the tk canvas not support png format, cannot save tkplot() output in png. if use tkplot() adjusting coordinates, use tkplot.getcoords() query adjusted coordinates , use plot() these coordinates create png file.

library(igraph) g <- graph.ring(10) id <- tkplot(g, edge.width=1:10) ## adjust coordinates hand, , continue. ## e.g. moved vertex 7 middle co <- tkplot.getcoords(id) png("output.png") plot(g, layout=co, edge.width=1:10) dev.off()

example output figure

i have following code - dictionary<string, string> mydict = new dictionary<string, string>(); mydict.add("keya", "valuea"); mydict.add("keyb", "valueb"); ienumerable<selectlistitem> myselectlist = new selectlist(mydict, "key", "value") further down in program, want add values mydict . possible? if yes, how? want - myselectlist.mydict.add("keyc", "valuec"); if you're wanting add items mydict, possible, , changes reflected in of myselectlist 's enumerations long changes made before enumeration (e.g. using .tolist() ) generated. as worked example: dictionary<string, string> mydict = new dictionary<string, string>(); mydict.add("keya", "valuea"); mydict.add("keyb", "valueb"); ienumerable<selectlistitem> myselectlist = new selectlist(mydict, "key", "value...
