How to rearrange diagram in R

Question

I updated my diagrammer to version 0.9.0 and started rendering different diagram from the same data. My data frame now looks like this:

df <-

You can also set these attributes with set_global_graph_attrs after creating the graph object.

I tried the above and failed when doing the following:

set_global_graph_attrs(
    graph = graph,
    attr = c("layout", "rankdir", "splines"),
    value = c("dot", "LR", "false"),
    attr_type = c("graph", "graph", "graph"))

render_graph(graph2)

The output would still have the same graph attributes as before.

Using the magrittr %>%then worked for me.

graph1 <-
   create_graph(
      nodes_df = ndf,
      edges_df = edf) %>%
   set_global_graph_attrs(
      attr = c("layout", "rankdir", "splines"),
      value = c("dot", "LR", "false"),
      attr_type = c("graph", "graph", "graph"))
