getPreprocessing {STATegRa} | R Documentation

## Retrieve information about preprocessing

### Description

Generic function to retrieve information about the preprocessing done by `omicsCompAnalysis` on a `caClass-class` object.

### Usage

    getPreprocessing(x, process=FALSE, preproData=FALSE, block=NULL)

### Arguments

`x` | `caClass-class` object.
`process` | Logical indicating whether to return information about the processing done.
`preproData` | Logical indicating whether to return the pre-processed data matrices.
`block` | Character indicating the block of data to be returned. It can be specified by the position of the block ("1" or "2") or the name assigned in the `caClass-class` object. If it is NULL both blocks are displayed.

### Value

If both `process` and `preproData` are specified, a list containing (otherwise the individual item):

process

  Character indicating the processing done

preproData

  Matrix (or list of matrices, depending on `block`) containing pre-processed data

    getPreprocessing(res, process=TRUE)
    getPreprocessing(res, preproData=TRUE, block="1")
