Extract or replace parts of an object

Description

Methods for extraction or replacements of parts of dual objects.

Usage

## S4 replacement method for signature 'dual,index,index,dual'
x[i, j, ...] <- value

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

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

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

## S4 replacement method for signature 'dual,index,index,logicalOrNumericOrArray'
x[i, j, ...] <- value

## S4 replacement method for signature 'dual,missing,index,logicalOrNumericOrArray'
x[i, j, ...] <- value

## S4 replacement method for signature 'dual,index,missing,logicalOrNumericOrArray'
x[i, j, ...] <- value

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

## S4 method for signature 'dual,index,index'
x[i, j, ..., drop = TRUE]

## S4 method for signature 'dual,missing,index'
x[i, j, ..., drop = TRUE]

## S4 method for signature 'dual,index,missing'
x[i, j, ..., drop = TRUE]

## S4 method for signature 'dual,missing,missing'
x[i, j, ..., drop = TRUE]

Arguments

x	dual object
i, j	indices of elements to extract or replace
...	supplementary indices (for arrays)
value	replacement value
drop	for dual matrices or array.

Value

returns a dual object (the semantic is the same as base extraction and replacement methods).

Examples

x <- c(1, 2, 3)
x[2] <- dual(4)
x
d(x)
