Examples

# Create a simple graph
nodes <-
  create_nodes(nodes = c("a", "b", "c", "d"),
               type = "letter",
               label = TRUE,
               value = c(3.5, 2.6, 9.4, 2.7))

edges <-
  create_edges(from = c("a", "b", "c"),
               to = c("d", "c", "a"),
               rel = "leading_to")

graph <-
  create_graph(nodes_df = nodes,
               edges_df = edges)

# Select nodes "a" and "c"
graph <- select_nodes(graph = graph, nodes = c("a", "c"))

# Verify that a node selection has been made
get_selection(graph)
#> $nodes
#> [1] "a" "c"

# Clear the selection
graph <- clear_selection(graph = graph)

# Verify that the node selection has been cleared
get_selection(graph)
#> [1] NA
