Welcome to the new bioconductor.org!


This is the development version of GDSArray; for the stable release version, see GDSArray.

Representing GDS files as array-like objects

Bioconductor version: Development (3.19)

GDS files are widely used to represent genotyping or sequence data. The GDSArray package implements the `GDSArray` class to represent nodes in GDS files in a matrix-like representation that allows easy manipulation (e.g., subsetting, mathematical transformation) in _R_. The data remains on disk until needed, so that very large files can be processed.
