DelayedDataFrame-method: DelayedDataFrame related methods.

In DelayedDataFrame: Delayed operation on DataFrame using standard DataFrame metaphor

Description

as.list, rbind would incur realization of the lazyIndex slot in DelayedDataFrame object.

cbind for DelayedDataFrame inherits the lazyIndex's if inputs have any DelayedDataFrame objects. Otherwise, return a new DelayedDataFrame with NULL lazyIndexes.

Usage

## S4 method for signature 'DelayedDataFrame'
as.list(x, use.names = TRUE)

## S4 method for signature 'DelayedDataFrame'
names(x)

## S4 method for signature 'DelayedDataFrame'
cbind(..., deparse.level = 1)

## S4 method for signature 'DelayedDataFrame'
bindROWS(
  x,
  objects = list(),
  use.names = TRUE,
  ignore.mcols = FALSE,
  check = TRUE
)

## S4 method for signature 'DelayedDataFrame,ANY'
extractROWS(x, i)

## S4 method for signature 'DelayedDataFrame'
extractCOLS(x, i)

## S4 method for signature 'DelayedDataFrame'
replaceCOLS(x, i, value)

## S4 method for signature 'DelayedDataFrame'
mergeROWS(x, i, value)

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

Arguments

x	as.list,DelayedDataFrame: a DelayedDataFrame object. OR, [,DelayedDataFrame: DelayedDataFrame object to be subsetted.
use.names	as.list,DelayedDataFrame: whether to use the colnames of DelayedDataFrame as the names for the returned list. OR, bindROWS,DelayedDataFrame: whether to use rownames of the input arguments. Default is TRUE.
...	cbind,DelayedDataFrame: One or more vector-like or matrix-like objects. These can be given as named arguments. OR, [,DelayedDataFrame: other arguments to pass.
deparse.level	See <e2><80><98>?base::cbind<e2><80><99> for a description of this argument.
objects	the DelayedDataFrame objects to be passed into bindROWS.
ignore.mcols	Logical. This argument is ignored for bindROWS,DelayedDataFrame.
check	Logical. This argument is ignored for bindROWS,DelayedDataFrame.
i	row subscript
value	the new values in the i,j subscripts of DelayedDataFrame object.
j	col subscript
drop	if drop with reduced dimension, default is TRUE.

Value

colnames of DelayedDataFrame
