R: Calculate normalization factors for URG method

URG_getFactor {Corbi} | R Documentation

## Calculate normalization factors for URG method

### Description

Calculate the normalization factor for each sample by using URG (uniform ratio graph) method.

### Usage

    URG_getFactor(expr.matrix, p.edge = 0.25, p.gene = 0.4, log.expr = FALSE)

### Arguments

`expr.matrix` | The expression matrix. Each row represents a gene and each column represents a sample.
`p.edge` | The percentage of gene pairs that are selected into the uniform ratio graph.
`p.gene` | The maximal percentage of genes that are selected as the stable genes.
`log.expr` | Logical variable indicating whether the input expression matrix is in logarithmic scale.

### Value

This function will return a numeric vector with each element [i] represents the normalization factor of sample (i).
