make_net_und {skynet}

Undirected Network

Description

Generates Undirected Network with an iGraph gUnd object, a Data Frame netUnd and a Data Frame with Airport/Nodes statistics nodes.

Usage

make_net_und(
  x,
  disp = FALSE,
  alpha = 0.003,
  cap = FALSE,
  pct = 10,
  merge = TRUE,
  carrier = FALSE,
  metro = FALSE
)

Arguments

x

Data frame

disp

Uses the Serrano's disparity filter (https://en.wikipedia.org/wiki/Disparity_filter_algorithm_of_weighted_network) to extract the backbone of the network.

alpha

Argument for disparity filter.

cap

Filters original data based on the edge weight.

pct

Argument for cap filter. Value should be imput as percentage.

merge

When set to FALSE, it keeps parallel edges instead of collapsing them and summing their weights.

carrier

Groups data per carrier and OD

metro

Groups data by metropolitan area

Examples

## Not run: 
make_net_und(OD_Sample)

# Apply Disparity Filter
make_net_und(OD_Sample, disp = TRUE, alpha = 0.05)

# Apply Percentage Cap
make_net_und(OD_Sample, cap = TRUE, pct = 20)

## End(Not run)
