r-bioc-delayedarray - 0.28.0+dfsg-1 main

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.
