readA: read A

Description

readA

Usage

readA(Afile, datfile, dat, annot = TRUE)

Arguments

Afile
The file which contains the matrix of sample contributions. It must be a txt file where the separator is white space, that is one or more spaces, tabs, newlines or carriage returns
datfile
The file which contains the matrix (of dimension features x samples) based on which the matrix A was calculated
dat
The data based on which the matrix A was calculated (features x samples)
annot
TRUE (default) if the Afile contains rownames of matrix A, FALSE if the rownames has to be extracted from dat

Value

This function returns a matrix of dimension samples x components with rownames filled with sample IDs.

Details

This function reads and annotates matrix A.

The matrix dat must be the one on which the matrix A was calculated. It is assumed that the number of components is lower than the number of samples, the matrix will be transposed to have dimension 'samples x components' according to this assumption. If annot is FALSE, colnames of dat are used to annotate rownames of A.
