With a graph object of class dgr_graph add nodes from a node data frame to that graph.

add_node_df(graph, node_df)

Arguments

graph

a graph object of class dgr_graph.

node_df

a node data frame that is created using create_node_df.

Value

a graph object of class dgr_graph.

Examples

# Create an empty graph graph <- create_graph() # Create a node data frame (ndf) ndf <- create_node_df( n = 4, type = "basic", color = c( "red", "green", "grey", "blue"), value = c( 3.5, 2.6, 9.4, 2.7)) # Add the node data frame to # the graph object to create # a graph with nodes graph <- graph %>% add_node_df( node_df = ndf) # Inspect the graph's ndf graph %>% get_node_df()
#> id type label color value #> 1 1 basic <NA> red 3.5 #> 2 2 basic <NA> green 2.6 #> 3 3 basic <NA> grey 9.4 #> 4 4 basic <NA> blue 2.7
# Create another node data frame ndf_2 <- create_node_df( n = 4, type = "basic", color = c( "white", "brown", "aqua", "pink"), value = c( 1.6, 6.4, 0.8, 4.2)) # Add the second node data # frame to the graph object # to add more nodes with # attributes to the graph graph <- graph %>% add_node_df( node_df = ndf_2) # View the graph's internal # node data frame using the # `get_node_df()` function graph %>% get_node_df()
#> id type label color value #> 1 1 basic <NA> red 3.5 #> 2 2 basic <NA> green 2.6 #> 3 3 basic <NA> grey 9.4 #> 4 4 basic <NA> blue 2.7 #> 5 5 basic <NA> white 1.6 #> 6 6 basic <NA> brown 6.4 #> 7 7 basic <NA> aqua 0.8 #> 8 8 basic <NA> pink 4.2
