getMatrix: Obtain a data matrix

In theMILOlab/SPATA2: A Toolbox for Spatial Expression Analysis

Obtain a data matrix

Description

Extracts a matrix or multiple matrices of molecular data.

Usage

getMatrix(object, mtr_name = NULL, ...)

## S4 method for signature 'SPATA2'
getMatrix(object, mtr_name = NULL, assay_name = activeAssay(object))

## S4 method for signature 'MolecularAssay'
getMatrix(object, mtr_name = NULL)

getMatrices(object, ...)

## S4 method for signature 'SPATA2'
getMatrices(object, assay_name = activeAssay(object), ...)

## S4 method for signature 'MolecularAssay'
getMatrices(object, ...)

Arguments

object	An object of class SPATA2 or, in case of S4 generics, objects of classes for which a method has been defined.
mtr_name	Character value. The name of the matrix to extract. If NULL, defaults to the active matrix of the provided or specified assay.
...	Used to absorb deprecated arguments or functions.
assay_name	Only relevant if the SPATA2 object contains more than one assay: Denotes the assay of interest and thus the molecular modality to use. Defaults to the active assay as set by activateAssay().

Value

A numeric matrix with rownames corresponding to molecule names and column names corresponding to barcodes. Or a named list of such in case of getMatrices().
