bind_graphs {tidygraph} | R Documentation |
Add graphs, nodes, or edges to a tbl_graph
Description
These functions are tbl_graph pendants to dplyr::bind_rows()
that allows
you to grow your tbl_graph
by adding rows to either the nodes data, the
edges data, or both. As with bind_rows()
columns are matched by name and
are automatically filled with NA
if the column doesn't exist in some
instances. In the case of bind_graphs()
the graphs are automatically
converted to tbl_graph
objects prior to binding. The edges in each graph
will continue to reference the nodes in the graph where they originated,
meaning that their terminal node indexes will be shifted to match the new
index of the node in the combined graph. This means the bind_graphs()
always result in a disconnected graph. See graph_join()
for merging graphs
on common nodes.
Usage
bind_graphs(.data, ...)
bind_nodes(.data, ...)
bind_edges(.data, ..., node_key = "name")
Arguments
.data |
A |
... |
In case of |
node_key |
The name of the column in |
Value
A tbl_graph
containing the new data
Examples
graph <- create_notable('bull')
new_graph <- create_notable('housex')
# Add nodes
graph %>% bind_nodes(data.frame(new = 1:4))
# Add edges
graph %>% bind_edges(data.frame(from = 1, to = 4:5))
# Add graphs
graph %>% bind_graphs(new_graph)
