mic_adj_matrix: Computes a MIC adjacency matrix

In vgasque/nutrigraph: Food Network Inference and Visualization

Description

For a given dataset, computes the adjacency matrix of maximal information coefficient (MIC) of each pairwise association. NOTE : another approach could have been to give the whole data frame to the minerva package func cstats(), but it seemed slower in my tests.

Usage

mic_adj_matrix(obs_data)

Arguments

obs_data

(data.frame or matrix) : a dataset which rows are observations and columns the variables.

Value

the adjacency matrix of MIC values for each pairwise association.
