Threshold network by density — thresholdNetwork • PhysioAnalysis

Thresholds a connectivity matrix to achieve a target network density.

Usage

thresholdNetwork(connectivity, density = 0.2, absolute = TRUE)

Arguments

connectivity: A connectivity matrix.
density: Target density (proportion of edges to keep, 0-1).
absolute: If TRUE, uses absolute values for ranking.

Value

A thresholded adjacency matrix.

Examples

set.seed(123)
pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(500 * 4), nrow = 500, ncol = 4)),
  samplingRate = 100
)
conn <- correlationMatrix(pe)
# Keep top 30% of connections
adj <- thresholdNetwork(conn, density = 0.3)
