extract: Extract or replace parts of an object

In acidgenomics/DESeqAnalysis: Acid Genomics DESeq2 Analysis Utilities

Extract or replace parts of an object

Description

Extract genes by row and samples by column.

Usage

## S4 method for signature 'DESeqAnalysis,ANY,ANY,ANY'
x[i, j, drop = FALSE]

Arguments

x	Object.
i	Indices specifying elements to extract or replace. Indices are numeric or character vectors, empty (missing), or NULL. For more information: help(topic = "Extract", package = "base")
j	Indices specifying elements to extract or replace. Indices are numeric or character vectors, empty (missing), or NULL. For more information: help(topic = "Extract", package = "base")
drop	For matrices and arrays. If TRUE the result is coerced to the lowest possible dimension (see the examples). This only works for extracting elements, not for the replacement. See drop for further details.

Value

DESeqAnalysis.
