get_ratio_variance: Calculate expression ratio variances

Description

Calculate the variances of expression ratios for each pair of genes.

Usage

get_ratio_variance(expr.matrix, log.expr = FALSE)

Arguments

expr.matrix

The expression matrix. Each row represents a gene and each column represents a sample.

log.expr

Logical variable indicating whether the input expression matrix is in logarithmic scale.

Value

This function will return a numeric matrix with element [i,j] represents the variance of expressioin ratios for gene pairs (i, j).
