'Layout_igraph_matrix' function not found

[soedr]

First off, thank you for making this package available, looking forward to using it.

Running through the example on your blog, I run into the following issue after calling:

> graph <- create_notable('zachary') %>% 
+  mutate(ranking = node_rank_leafsort())
> ggraph(graph, 'matrix') + 
+  geom_edge_point(mirror = TRUE) + 
+  theme_graph() + 
+  coord_fixed()
Error in layout_igraph_matrix(list(34, FALSE, c(1, 2, 3, 4, 5, 6, 7, 8,  : 
  could not find function "layout_igraph_matrix"

Did I miss something?

I did not mention it in the blog post but the graphics depend on the development version of ggraph - install From thomasp85/ggraph
