In DiagrammeR: Graph/Network Visualization

Deselect any selected nodes in a graph

Description

Deselect nodes in a graph object of class dgr_graph.

Usage

deselect_nodes(graph, nodes)

Arguments

graph	A graph object of class dgr_graph.
nodes	A vector of node IDs that should be deselected.

Value

A graph object of class dgr_graph.

Examples

# Create a node data frame (ndf)
ndf <-
  create_node_df(
    n = 4,
    type = c("a", "a", "z", "z"),
    label = TRUE,
    value = c(3.5, 2.6, 9.4, 2.7))

# Create an edge data frame (edf)
edf <-
  create_edge_df(
    from = c(1, 2, 3),
    to = c(4, 3, 1),
    rel = c("a", "z", "a"))

# Create a graph with the ndf and edf
graph <-
  create_graph(
    nodes_df = ndf,
    edges_df = edf)

# Explicitly select nodes `1` and `3`
graph <-
  graph %>%
  select_nodes(nodes = c(1, 3)) %>%
  deselect_nodes(nodes = 1)

# Verify that the node selection
# has been made for nodes `1` and
# `3` and that node `1` has been
# deselected (leaving only `3`)
graph %>% get_selection()
