fsEdger: Selects Features by Exact Test

Description Usage Arguments Details Value

View source: R/5.1-fs.R

Description

fsEdger selects features using the exactTest function from the edgeR package. This function does not normalize the data, but does estimate dispersion using the estimateCommonDisp and estimateTagwiseDisp functions.

Usage

1
fsEdger(object, top = 0, ...)

Arguments

object

An ExprsArray object to undergo feature selection.

top

A numeric scalar or character vector. A numeric scalar indicates the number of top features that should undergo feature selection. A character vector indicates specifically which features by name should undergo feature selection. Set top = 0 to include all features. A numeric vector can also be used to indicate specific features by location, similar to a character vector.

...

Arguments passed to the detailed function.

Details

The user can normalize the data before feature selection using the modTMM function. Note that applying edgeR to already normalized counts differs slightly from applying edgeR with normalization.

Value

Returns an ExprsArray object.
