GDCquery {TCGAbiolinks} | R Documentation

## Query GDC data

### Description

Uses GDC API to search for search, it searches for both controlled and open-access data. For GDC data arguments project, data.category, data.type and workflow.type should be used For the legacy data arguments project, data.category, platform and/or file.extension should be used. Please, see the vignette for a table with the possibilities.

### Usage

    GDCquery(
      project,
      data.category,
      data.type,
      workflow.type,
      legacy = FALSE,
      access,
      platform,
      file.type,
      barcode,
      data.format,
      experimental.strategy,
      sample.type
    )
