Description

This function computes the relative gene expression (log2 counts) in a sample w.r.t. all samples.

Usage

relativeExpr(expr, power = 1)

Arguments

expr

A matrix of expression data (log2 counts), with gene per row and sample per column.

power

The power n of relative expression: (x^n/<x>)^(1/n). Default: 1.

Value

A matrix of relative log2 counts.

Examples

# NOT RUN {
data(exprMaguire)
relExpr1 <- relativeExpr(exprMaguire$expr, 1)
# }
