In llrs/STATegRa: Classes and methods for multi-omics data integration

Description

Generic function to retrieve loadings (common and distinctive) found by omicsCompAnalysis on a caClass-class object.

Usage

getLoadings(x, part=NULL, block=NULL)

Arguments

x	caClass-class object.
part	Character indicating whether "common" or "distinctive" loadings should be displayed
block	Character indicating the block of data for which the loadings will be given. 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

A list containing the requested information.
