Problems of Converting Graphs to Chart Chart
I like to use igraph
to create and manage graphs, and I want to use DiagrammeR
to make nice visualization of graphs. I am having trouble converting my charts to DiagrammeR
.
> library(igraph)
> library(DiagrammeR)
> g = make_empty_graph() + vertices(c("a", "b")) + edge("a", "b")
> x = from_igraph(g)
Warning messages:
1: In data.frame(from = as.integer(igraph::ends(igraph, igraph::E(igraph))[, :
NAs introduced by coercion
2: In data.frame(from = as.integer(igraph::ends(igraph, igraph::E(igraph))[, :

This is for drake which is highly dependent igraph
and I don't want to convert the internals to DiagrammeR
.
