computeZScore {singleCellTK} | R Documentation

## Compute Z-Score

### Description

Computes Z-Score from an input count matrix using the formula ((x-mean(x))/sd(x)) for each gene across all cells. The input count matrix can either be a base matrix, dgCMatrix or a DelayedMatrix. Computations are performed using DelayedMatrixStats package to efficiently compute the Z-Score matrix.

### Usage

    computeZScore(counts)

### Arguments

`counts` | matrix (base matrix, dgCMatrix or DelayedMatrix)

### Value

z-score computed counts matrix (DelayedMatrix)

### Examples

    data(sce_chcl, package = "scds")
    assay(sce_chcl, "countsZScore") <- computeZScore(assay(sce_chcl, "counts"))
