ReshapedHDF5ArraySeed-class: ReshapedHDF5ArraySeed objects

In HDF5Array: HDF5 backend for DelayedArray objects

Description

ReshapedHDF5ArraySeed is a low-level helper class for representing a pointer to a virtually reshaped HDF5 dataset.

ReshapedHDF5ArraySeed objects are not intended to be used directly. Most end users should create and manipulate ReshapedHDF5Array objects instead. See ?ReshapedHDF5Array for more information.

Usage

## Constructor function:
ReshapedHDF5ArraySeed(filepath, name, dim, type=NA)

Arguments

filepath, name, dim, type

See ?ReshapedHDF5Array for a description of these arguments.

Details

No operation can be performed directly on a ReshapedHDF5ArraySeed object. It first needs to be wrapped in a DelayedArray object. The result of this wrapping is a ReshapedHDF5Array object (a ReshapedHDF5Array object is just a ReshapedHDF5ArraySeed object wrapped in a DelayedArray object).

Value

A ReshapedHDF5ArraySeed object.

Examples

library(h5vcData)
tally_file <- system.file("extdata", "example.tally.hfs5",
                          package="h5vcData")

library(rhdf5)  # for h5ls()
h5ls(tally_file)

## Collapse the first 2 dimensions:
seed <- ReshapedHDF5ArraySeed(tally_file, "/ExampleStudy/16/Coverages",
                              dim=c(12, 90354753))
