a graph object of class dgr_graph.

edge_attr_from

edge_attr_to

the new name of the edge attribute column identified in edge_attr_from.

Examples

# Create a random graph using the # `add_gnm_graph()` function graph <- create_graph() %>% add_gnm_graph( n = 5, m = 8, set_seed = 23) %>% set_edge_attrs( edge_attr = color, values = "green") # Get the graph's internal edf # to show which edge attributes # are available graph %>% get_edge_df()
#> id from to rel color #> 1 1 1 3 <NA> green #> 2 2 2 1 <NA> green #> 3 3 2 5 <NA> green #> 4 4 2 3 <NA> green #> 5 5 3 2 <NA> green #> 6 6 3 5 <NA> green #> 7 7 3 4 <NA> green #> 8 8 5 3 <NA> green
# Rename the `color` node # attribute as `weight` graph <- graph %>% rename_edge_attrs( edge_attr_from = color, edge_attr_to = labelfontcolor) # Get the graph's internal # edf to show that the edge # attribute had been renamed graph %>% get_edge_df()
#> id from to rel labelfontcolor #> 1 1 1 3 <NA> green #> 2 2 2 1 <NA> green #> 3 3 2 5 <NA> green #> 4 4 2 3 <NA> green #> 5 5 3 2 <NA> green #> 6 6 3 5 <NA> green #> 7 7 3 4 <NA> green #> 8 8 5 3 <NA> green
