Generates a bigger graph by linear growth.

generate_graph_linear.Rd

Generates a bigger graph using parameters for node and edge growth. If a sequence of graphs are created, the number of nodes would linearly increase.

Usage

generate_graph_linear(
  gr = NULL,
  del_edge = 1,
  new_nodes = 1,
  edge_increase = 1,
  edges_per_new_node = 3
)

Arguments

gr

The input graph to generate the next graph. If set to NULL a graph using igraph::sample_pa is used as the input graph.

del_edge

The number of edges deleted from the input graph. Default set to 1.

new_nodes

The number of nodes added to the input graph. Default set to 1.

edge_increase

The number of edges added to the input graph. Default set to 1.

edges_per_new_node

The number of edges added to the new nodes. Default set to 3.

Value

A graph.

Examples

set.seed(1)
gr <- generate_graph_linear()
gr
#> IGRAPH f3ae14a U--- 11 12 -- Barabasi graph
#> + attr: name (g/c), power (g/n), m (g/n), zero.appeal (g/n), algorithm

#> + edges from f3ae14a:
