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

this question has answer here: why write “.call(this)” @ end of javascript anonymous function? [duplicate] 4 answers what kind of design pattern , significance of using closure? (function(){ // code here }).call(this); edit then difference between above code , following this keyword still refer same object in both ways. (function(){ // code here })(); thats invoked function expression. more info here: http://benalman.com/news/2010/11/immediately-invoked-function-expression/ the purpose run code while protecting scope (so variables declared within don't leak out global scope. update call sets value of this function being applied on. without it, value set window object, there set outer scope.
