DataSpace: The DataSpace Class

Description Usage Arguments

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.
