get_ratio_variance {Corbi} | R Documentation

## 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).
