DataSpace: The DataSpace Class

In h5: Interface to the 'HDF5' Library

Description

The DataSpace class used to select data elements from DataSet objects. DataSpace objects can be generated using the S4–method selectDataSpace from DataSets objects in 3 ways:

1. Without any parameters: Select all elements in DataSet.

2. With offset and count: Select contiguous sub–region (hyperslab) from DataSet.

3. With parameter elem: Select sub-elements specified by matrix holding selected indices. This selection type can become slow for many data points.

Usage

## S4 method for signature 'DataSpace'
h5close(.Object)

selectDataSpace(.Object, offset = rep(NA_integer_, length(.Object@dim)),
  count = rep(NA_integer_, length(.Object@dim)), elem)

## S4 method for signature 'DataSet,missing,missing,missing'
selectDataSpace(.Object)

## S4 method for signature 'DataSet,ANY,ANY,missing'
selectDataSpace(.Object, offset, count)

## S4 method for signature 'DataSet,missing,missing,matrix'
selectDataSpace(.Object, elem)

Arguments

.Object	DataSet; S4 object of class DataSet (DataSpace for h5close).
offset	numeric; Offset to be selected from Hyperslab.
count	numeric; Count to be selected from Hyperslab.
elem	matrix; Matrix specifying element selection coordinates. Columns specify rank, rows specify different points.
...	additional arguments passed to c.
