Extract or replace chunk blocks from an array

Convenience wrappers around [ to extract or replace blocks from an array based on block coordinates.

Usage

chunk_blocks(x, ..., drop = TRUE, origin = chunk_origin(x))

chunk_blocks(x, ..., origin = chunk_origin(x)) <- value

x: Object from which to extract element(s) or in which to replace element(s).
...: block coordinates specifying elements to extract or replace. Can be numeric, logical, or missing. If numeric, the coordinates will be mapped to indices unless there is a single, non-matrix argument.
drop: if TRUE the result is coerced to the lowest possible dimension.
origin: the origin of the chunk array, used for mapping coordinates to indices
value: An array-like R object of similar class as x
