R/Bioconductor Package for interfacing with Snaptron for rapid querying of expression counts

Bioconductor version: Release (3.19)

snapcount is a client interface to the Snaptron webservices which support querying by gene name or genomic region. Results include raw expression counts derived from alignment of RNA-seq samples and/or various summarized measures of expression across one or more regions/genes per-sample (e.g. percent spliced in).
