TCGAretriever (version 1.9.1)

TCGAretriever-package: Retrieve Genomic and Clinical Data from CBioPortal

Description

The Cancer Genome Atlas (TCGA) is a scientific and medical program aimed at improving our understanding of Cancer Biology. Part of the TCGA Datasets (free-access tier) are hosted on cBioPortal, which is an open-access, open-source resource for interactive exploration of multidimensional cancer genomics data sets. TCGAretriever helps accessing and downloading TCGA data via the cBioPortal API. Features of TCGAretriever are:

• it is simple and reliable

• it is tailored for downloading large volumes of data
