I was looking for an example or tutorial to convert a ggraph object to an iterative force network.

First I tried to convert to plotly object using plotly::ggplotly function. But seems the plotly don't deal nicely with this kind of conversion and miss the edges.

But I find the network3D, I can convert an igraph object to a network3D object, but it is not what I wanted. And this package has too verbose functions. Anyway, there is no function to convert from ggraph object.

So, my question is really basic but... Do you know any method to crate an interactive ggraph network?

Thanks

Try the ggiraph package, it works with ggraph as you can see in the example here (bottom of the page).

For future reference (if the above link may die), here's the example of ggiraph (not my code):

library(ggraph)
library(igraph)
library(ggiraph)

actors <- data.frame(
  name = c("Alice", "Bob", "Cecil", "David", "Esmeralda"),
  age = c(48,33,45,34,21),
  gender = c("F","M","F","M","F")
)
relations <- data.frame(
  from = c("Bob", "Cecil", "Cecil", "David", "David", "Esmeralda"),
  to = c("Alice", "Bob", "Alice", "Alice", "Bob", "Alice"),
  same.dept = c(FALSE,FALSE,TRUE,FALSE,FALSE,TRUE),
  friendship = c(4,5,5,2,1,1),
  advice = c(4,5,5,4,2,3)
)

g <- graph_from_data_frame(relations,
       directed = TRUE, vertices = actors)

z <- ggraph(g, layout = 'linear', circular = TRUE) +
  geom_edge_arc(color = "red", edge_width = .2) +
  geom_point_interactive(size = 5,
    mapping = aes(x = x, y = y, data_id = gender,
                  tooltip = paste0(name, ": ", age, "y.o."))
  ) + theme_graph()

girafe(ggobj = z, width_svg = 5, height_svg = 5,
       options = list(opts_sizing(rescale = FALSE)))

It seems plotly does not support ggraph yet, but you can track the progress here.
