Package

r-delayedarray

Description

A unified framework for working transparently with on-disk and in-memory
array-like datasets. Wrapping an array-like object (typically an on-disk
object) in a DelayedArray object allows one to perform common array
operations on it without loading the object in memory. In order to
reduce memory usage and optimize performance, operations on the object
are either delayed or executed using a block processing mechanism. Note
that this also works on in-memory array-like objects like DataFrame
objects (typically with Rle columns), Matrix objects, and ordinary
arrays and data frames.
