Change terminal nodes of edges
The reroute verb lets you change the beginning and end node of edges by specifying the new indexes of the start and/or end node(s). Optionally only a subset of the edges can be rerouted using the subset argument, which should be an expression that are to be evaluated in the context of the edge data and should return an index compliant vector (either logical or integer).
reroute(.data, from = NULL, to = NULL, subset = NULL)
.data |
A tbl_graph or morphed_tbl_graph object. grouped_tbl_graph will be ungrouped prior to rerouting |
from, to |
The new indexes of the terminal nodes. If |
subset |
An expression evaluating to an indexing vector in the context of the edge data. |
An object of the same class as .data
# Switch direction of edges
create_notable('meredith') %>%
activate(edges) %>%
reroute(from = to, to = from)
# Using subset
create_notable('meredith') %>%
activate(edges) %>%
reroute(from = 1, subset = to > 10)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
