threshold: Apply thresholds to a score or loading matrix

In jonalim/mfBiclust: Pipelines for Bi-Clustering Using Matrix Factorization

Description

Returns a binary matrix of the same size as m where all elements over the threshold are 1.

Usage

threshold(m, th, MARGIN = 2)

## S4 method for signature 'matrix,numeric'
threshold(m, th, MARGIN = 2)

Arguments

m	A numeric matrix
th	A numeric vector with the same number of elements as dim(m)[[MARGIN]]
MARGIN	1 to threshold rows; 2 to threshold columns.

Value

A binary numeric matrix of the same dimensions as m

Methods (by class)

• m = matrix,th = numeric: Apply threshold to a score or loading matrix

Examples

m <- matrix(rnorm(100), 10, 10)
m
threshold(m = m, th = rep(0, 10), MARGIN = 1)
