# Get count of edge definitions where multiple edges occur

Source:`R/get_edge_count_w_multiedge.R`

`get_edge_count_w_multiedge.Rd`

Get a count of the number of edge definitions (e.g, `1`

-> `2`

) where there
are multiple edges (i.e., more than 1 edge of that definition, having
distinct edge ID values). So, for example, if there are 2 edge definitions in
the graph that involve 6 separate edge IDs (3 such edge IDs for each of the
pairs of nodes), the count will be `2`

.

## Examples

```
# Create a node data frame (ndf)
ndf <-
create_node_df(
n = 5,
label = TRUE)
# Create an edge data frame (edf)
edf <-
create_edge_df(
from = c(1, 4, 4, 3, 5, 1, 3, 4),
to = c(4, 1, 1, 2, 2, 2, 2, 1))
# Create a graph with the ndf and edf
graph <-
create_graph(
nodes_df = ndf,
edges_df = edf)
# Get the total number of edge
# definitions (e.g., `4` -> `1`) where
# there are multiple edges (i.e.,
# distinct edges with separate edge
# ID values)
graph %>% get_edge_count_w_multiedge()
#> [1] 2
```
