mark_select function

Marking nodes for selection based on measures

These functions return logical vectors the length of the nodes in a network identifying which hold certain properties or positions in the network.

• node_is_random() marks one or more nodes at random.
• node_is_max() and node_is_min() are more generally useful for converting the results from some node measure into a mark-class object. They can be particularly useful for highlighting which node or nodes are key because they minimise or, more often, maximise some measure.

node_is_random(.data, size = 1)

node_is_max(node_measure, ranks = 1)

node_is_min(node_measure, ranks = 1)

Arguments

• .data: An object of a manynet-consistent class:

  • matrix (adjacency or incidence) from {base} R
  • edgelist, a data frame from {base} R or tibble from {tibble}
  • igraph, from the {igraph} package
  • network, from the {network} package
  • tbl_graph, from the {tidygraph} package

• size: The number of nodes to select (as TRUE).

• node_measure: An object created by a node_ measure.

• ranks: The number of ranks of max or min to return. For example, ranks = 3 will return TRUE for nodes with scores equal to any of the top (or, for node_is_min(), bottom) three scores. By default, ranks = 1.

Examples

node_is_random(ison_brandes, 2)
#node_is_max(migraph::node_degree(ison_brandes))
#node_is_min(migraph::node_degree(ison_brandes))
