library(cBioPortalData)
library(AnVIL)This vignette lays out the two main user-facing functions for downloading
and representing data from the cBioPortal API. cBioDataPack
makes use of the legacy distribution data method in cBioPortal (via
tarballs). cBioPortalData allows for a more flexibile approach to obtaining
data based on several available parameters including available molecular
profiles.
This function will access the packaged data from and return an integrative MultiAssayExperiment representation.
cBioDataPack("laml_tcga")## A MultiAssayExperiment object of 11 listed
## experiments with user-defined names and respective classes.
## Containing an ExperimentList class object of length 11:
## [1] CNA: SummarizedExperiment with 24776 rows and 191 columns
## [2] RNA_Seq_expression_median: SummarizedExperiment with 19720 rows and 179 columns
## [3] RNA_Seq_mRNA_median_Zscores: SummarizedExperiment with 19720 rows and 179 columns
## [4] RNA_Seq_v2_expression_median: SummarizedExperiment with 20531 rows and 173 columns
## [5] RNA_Seq_v2_mRNA_median_Zscores: SummarizedExperiment with 20531 rows and 173 columns
## [6] cna_hg19.seg: RaggedExperiment with 13571 rows and 191 columns
## [7] linear_CNA: SummarizedExperiment with 24776 rows and 191 columns
## [8] methylation_hm27: SummarizedExperiment with 10919 rows and 194 columns
## [9] methylation_hm450: SummarizedExperiment with 10919 rows and 194 columns
## [10] mutations_extended: RaggedExperiment with 2584 rows and 197 columns
## [11] mutations_mskcc: RaggedExperiment with 2584 rows and 197 columns
## Features:
## experiments() - obtain the ExperimentList instance
## colData() - the primary/phenotype DFrame
## sampleMap() - the sample availability DFrame
## `$`, `[`, `[[` - extract colData columns, subset, or experiment
## *Format() - convert into a long or wide DFrame
## assays() - convert ExperimentList to a SimpleList of matricesThis function provides a more flexible and granular way to request a MultiAssayExperiment object from a study ID, molecular profile, gene panel, sample list.
