DataSpace: The DataSpace Class

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

"h5close"(.Object)


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


"selectDataSpace"(.Object)


"selectDataSpace"(.Object, offset, count)


"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.
