GEOquery: Get data from NCBI Gene Expression Omnibus (GEO)

The NCBI Gene Expression Omnibus (GEO) is a public repository of high-throughput functional genomics data, including microarray, RNA-seq, and single-cell experiments. GEOquery is the bridge between GEO and Bioconductor: it downloads and parses GEO Series (GSE), Sample (GSM), Platform (GPL), and DataSet (GDS) records. By default it parses GEO Series Matrix files into Bioconductor 'ExpressionSet' objects; it can also parse the full SOFT format into GEOquery's own S4 classes, retrieve NCBI-computed RNA-seq quantifications, download supplementary files, and search GEO.
