scater (version 1.0.4)

norm_exprs: Accessors for the 'norm_exprs' (normalised expression) element of an SCESet object.

Description

The norm_exprs element of the arrayData slot in an SCESet object holds a matrix containing normalised expression values. It has the same dimensions as the 'exprs' and 'counts' elements, which hold the transformed expression data and count data, respectively.

Usage

norm_exprs(object)
norm_exprs(object) <- value
"norm_exprs"(object)
"norm_exprs"(object)<-value
"norm_exprs"(object)
"norm_exprs"(object) <- value

Arguments

object

a SCESet object.

value

an integer matrix

Value

a matrix of normalised expression data

Details

The default for normalised expression values is mean-centred and variance-standardised expression data from the exprs slot of the SCESet object. The function normaliseExprs (or normalizeExprs) provides more options and functionality for normalising expression data.

Examples

data("sc_example_counts")
data("sc_example_cell_info")
example_sceset <- newSCESet(countData = sc_example_counts)
norm_exprs(example_sceset)
