# path

From igraph v1.2.5
by Gabor Csardi

##### Helper function to add or delete edges along a path

This function can be used to add or delete edges that form a path.

##### Usage

`path(...)`

##### Arguments

- ...
See details below.

##### Details

When adding edges via `+`

, all unnamed arguments are
concatenated, and each element of a final vector is interpreted
as a vertex in the graph. For a vector of length \(n+1\), \(n\)
edges are then added, from vertex 1 to vertex 2, from vertex 2 to vertex
3, etc. Named arguments will be used as edge attributes for the new
edges.

When deleting edges, all attributes are concatenated and then passed
to `delete_edges`

.

##### Value

A special object that can be used together with igraph graphs and the plus and minus operators.

##### Examples

```
# NOT RUN {
# Create a (directed) wheel
g <- make_star(11, center = 1) + path(2:11, 2)
plot(g)
g <- make_empty_graph(directed = FALSE, n = 10) %>%
set_vertex_attr("name", value = letters[1:10])
g2 <- g + path("a", "b", "c", "d")
plot(g2)
g3 <- g2 + path("e", "f", "g", weight=1:2, color="red")
E(g3)[[]]
g4 <- g3 + path(c("f", "c", "j", "d"), width=1:3, color="green")
E(g4)[[]]
# }
```
