compareSteady {INSPEcT} | R Documentation

## Generate an object of class INSPEcT_diffsteady from an object of class INSPEcT

### Description

This method compares two object of class INSPEcT in order to identify differential usage of synthesis, processing or degradation rates in two different steady-state conditions. The two INSPEcT objects must have been profiled with replicates in order to provide a statistical significance to the differences between their rates.

### Usage

    compareSteady(inspectIds, BPPARAM = SerialParam())

    ## S4 method for signature 'INSPEcT'
    compareSteady(inspectIds, BPPARAM = SerialParam())

### Arguments

`inspectIds` | An object of calss INSPEcT with two conditions
`BPPARAM` | Configuration for BiocParallel parallelization. By default is set to SerialParam()

### Value

An object of class INSPEcT_diffsteady which contains both the absolute quantification of the rates as well as the comparison with the statistical significance associated for each gene and rate. (See `INSPEcT_diffsteady-class`)

### Examples
