Feature-Level Meta Data

Description

Get and set feature-level meta data

Usage

## S3 method for class 'StdAssay'
x[[i, j, ..., drop = FALSE]]

## S3 method for class 'StdAssay'
head(x, n = 10L, ...)

## S3 method for class 'StdAssay'
tail(x, n = 10L, ...)

## S4 replacement method for signature 'StdAssay,character,missing,data.frame'
x[[i, j, ...]] <- value

## S4 replacement method for signature 'StdAssay,missing,missing,data.frame'
x[[i, j, ...]] <- value

## S4 replacement method for signature 'StdAssay,character,missing,factor'
x[[i, j, ...]] <- value

## S4 replacement method for signature 'StdAssay,character,missing,NULL'
x[[i, j, ...]] <- value

## S4 replacement method for signature 'StdAssay,character,missing,vector'
x[[i, j, ...]] <- value

## S4 replacement method for signature 'StdAssay,numeric,missing,ANY'
x[[i, j, ...]] <- value

## S4 replacement method for signature 'StdAssay,missing,missing,NULL'
x[[i, j, ...]] <- value

Arguments

x	An Assay5 object
i	Name of feature-level meta data to fetch or add
