TI, WI calculator for R

Input data frame should be without header, the columns should be ordered: node name of species A, node name of species B, weight. Symmetrization_method is optional, can be either 'sum' (default), 'average', 'max', 'min' or 'difference.' Multilink edges will be summed.

If input data does not contain weights (3rd column), then only TI will be calculated.

calculate_TI_WI <- function(input_data, steps, symmetrization_method="sum") {
    ...
}

Input data should be an edge list without header:

node A	node B	weight
A	B	1.12
B	C	0.12
A	D	2.23

Use the script like this:

1. Import the function calculate_TI_WI.R.
2. Import the dataset to a data frame you want to use.
3. Calculate the TI and WI indeces with 3 steps.

source("calculate_TI_WI.R")
df = read.table("abcd.txt")
result = calculate_TI_WI(df, 3)
