bioconductor-gdsfmt

name	bioconductor-gdsfmt
description	Provides a high-level R interface to CoreArray Genomic Data Structure (GDS) data files. GDS is portable across platforms with hierarchical structure to store multiple scalable array-oriented data sets with metadata information. It is suited
when_to_use	Use when: Storing and managing large-scale array-oriented datasets that are much larger than available random-access memory using createfn.gds.; Writing and compressing low-bit integer data (e.g., 2-bit integers for genotypes) using add.gdsn with storage="bit2".; Applying user-defined functions marginally across rows or columns of massive matrices using apply.gdsn.; Reading specific subsets of compressed da. Not for: For small datasets that easily fit in memory; use standard R matrix or data.frame objects because GDS file creation adds unnecessary overhead.; For purely sparse matrix operations without disk-backing; use the Matrix package directly (e.g., dgCMatrix

When to Use

• Storing and managing large-scale array-oriented datasets that are much larger than available random-access memory using createfn.gds.
• Writing and compressing low-bit integer data (e.g., 2-bit integers for genotypes) using add.gdsn with storage="bit2".
• Applying user-defined functions marginally across rows or columns of massive matrices using apply.gdsn.
• Reading specific subsets of compressed data efficiently using read.gdsn or .
