Create adjacency matrix from connectivity

Source: R/ops-network.R
adjacencyMatrix.Rd

Converts a connectivity matrix into an adjacency matrix for network analysis.

Usage

adjacencyMatrix(connectivity, threshold = NULL, absolute = FALSE)

Arguments

connectivity

A connectivity matrix or result from connectivityMatrix().

threshold

Threshold value for binarization. If NULL, keeps weighted edges.

absolute

If TRUE, uses absolute values before thresholding.

Value

A square adjacency matrix.

Examples

set.seed(123)
pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(500 * 4), nrow = 500, ncol = 4)),
  samplingRate = 100
)
conn <- correlationMatrix(pe)
adj <- adjacencyMatrix(conn, threshold = 0.3)
