## Size: 3.31 kBcgdsr (Clinical)getClinicalData uses case_list_id as input without specifying the
study_id as case list identifiers are unique to each study.We query clinical data for the gbm_tcga_pub_expr_classical case list
identifier which is part of the gbm_tcga_pub study.
getClinicalData.CGDS(x = cgds,
caseList = "gbm_tcga_pub_expr_classical"
)cgdsr allows you to obtain clinical data for a case list subset
(54 cases with gbm_tcga_pub_expr_classical) and cBioPortalData provides
clinical data for all 206 samples in gbm_tcga_pub using the clinicalData
function.
cgdsr returns a data.frame with sampleId (TCGA.02.0009.01) but not
patientId (TCGA.02.0009)cBioPortalData returns sampleId (TCGA-02-0009-01) and patientId
(TCGA-02-0009).cgdsr provides case_ids with . and cBioPortalData returns patientIds
with -.You may be interested in other clinical data endpoints. For a list, use

function, if you only have Hugo symbols. First, convert to Entrez gene IDs
and then obtain all the samples in the sample list of interest.

cgdsr (Profile Data)The getProfileData function allows for straightforward retrieval of the
molecular profile data with only a case list and genetic profile identifiers.

data depending on the use case. Note that molecularData is mostly used
internally and that the cBioPortalData function is the user-friendly method
for downloading such data.
