cgdsr (version 1.3.0)

cgdsr-getGeneticProfiles: Get available genetic data profiles for a specific cancer study

Description

Queries the CGDS API and returns the available genetic profiles, e.g. mutation or copy number profiles, stored about a specific cancer study.

Usage

# S3 method for CGDS
getGeneticProfiles(x,cancerStudy,...)

Arguments

x

A CGDS object (required)

cancerStudy

cancer study ID (required)

...

Not used.

Value

A data.frame with six columns:

1. genetic_profile_id: a unique ID used to identify the genetic profile ID in subsequent interface calls. This is a human readable ID. For example, "gbm_tcga_mutations" identifies the TCGA GBM mutation genetic profile.

2. genetic_profile_name: short profile name.

3. genetic_profile_description: short profile description.

4. cancer_study_id: cancer study ID tied to this genetic profile. Will match the input cancer_study_id.

5. genetic_alteration_type: indicates the profile type. Will be one of: MUTATION, MUTATION_EXTENDED, COPY_NUMBER_ALTERATION, MRNA_EXPRESSION.

6. show_profile_in_analysis_tab: a boolean flag used for internal purposes (you can safely ignore it).
