33 cancer types. Use sampleTables on the MultiAssayExperiment object
along with data(sampleTypes, package = "TCGAutils") to see what samples are
present in the data. There may be tumors that were used to create multiple
contributions leading to technical replicates. These should be resolved using
the appropriate helper functions such as mergeReplicates. Primary tumors
should be selected using TCGAutils::TCGAsampleSelect and used as input
to the subsetting mechanisms. See the “Samples in Assays” section of this
vignette.

MultiAssayExperiment vignette.
Some cancer datasets contain associated subtype information within the
clinical datasets provided. This subtype information is included in the
metadata of colData of the MultiAssayExperiment object. To obtain these
variable names, use the getSubtypeMap function from TCGA utils:
head(getSubtypeMap(accmae))## ACC_annotations ACC_subtype

## 3 mrna_subtypes C1A/C1B

## 5 cimp MethyLevel
## 6 microrna_subtypes miRNA clusterAnother helper function provided by TCGAutils allows users to obtain a set
of consistent clinical variable names across several cancer types.
Use the getClinicalNames function to obtain a character vector of common
clinical variables such as vital status, years to birth, days to death, etc.

## 90You can use the reference dataset (sampleTypes) from the TCGAutils package
to interpret the TCGA sample codes above. The dataset provides clinically
meaningful descriptions:
data(sampleTypes, package = "TCGAutils")
head(sampleTypes)## Code Definition Short.Letter.Code

## 5 05 Additional - New Primary TAP
## 6 06 Metastatic TMOften, an analysis is performed comparing two groups of samples to each other.
To facilitate the separation of samples, the splitAssays TCGAutils function
identifies all sample types in the assays and moves each into its own
assay. By default, all discoverable sample types are separated into
a separate experiment. In this case we requested only solid tumors and blood
derived normal samples as seen in the sampleTypes reference dataset:
sampleTypes[sampleTypes[["Code"]] %in% c("01", "10"), ]## Code Definition Short.Letter.Code
## 1 01 Primary Solid Tumor TP
## 10 10 Blood Derived Normal NBsplitAssays(accmae, c("01", "10"))## Warning: 'splitAssays' is deprecated.

## assays() - convert ExperimentList to a SimpleList of matrices
## exportClass() - save data to flat filesTo obtain a logical vector that could be used for subsetting a
MultiAsssayExperiment, refer to TCGAsampleSelect. To select only primary
tumors, use the function on the colnames of the MultiAssayExperiment:
tums <- TCGAsampleSelect(colnames(accmae), "01")If interested in only the primary tumor samples, TCGAutils provides a
convenient operation to extract primary tumors from the MultiAssayExperiment
representation. The TCGAprimaryTumors function will return only
samples with primary tumor (either solid tissue or blood) samples using
the above operations in the background:
(primaryTumors <- TCGAprimaryTumors(accmae))## harmonizing input:

## 90When extracting a single assay from the MultiAssayExperiment the user
can conveniently choose to keep the colData from the MultiAssayExperiment
in the extracted assay given that the class of the extracted assay
supports colData storage and operations. SummarizedExperiment and its
derived data representations support this operation. In this example, we
extract the mutation data as represented by a RaggedExperiment which was
designed to have colData functionality. The default replacement method
is to ‘append’ the MultiAssayExperiment colData to the RaggedExperiment
assay. The mode argument can also completely replace the colData when set
to ‘replace’.

internal representation. Typical use of a RaggedExperiment involves a number of
functions to reshape ‘ragged’ measurements into a matrix-like format. These
include sparseAssay, compactAssay, disjoinAssay, and qreduceAssay.
See the RaggedExperiment vignette for details. In this example, we convert
entrez gene identifiers to numeric in order to show how we can create a sparse
matrix representation of any numeric metadata column in the RaggedExperiment.
ragex <- accmae[["ACC_Mutation-20160128"]]
## convert score to numeric

## <89 more elements>MultiAssayExperiment provides users with an integrative representation of multi-omic TCGA data at the convenience of the user. For those users who wish to use alternative environments, we have provided an export function to extract all the data from a MultiAssayExperiment instance and write them to a series of files:
td <- tempdir()
tempd <- file.path(td, "ACCMAE")
if (!dir.exists(tempd))
dir.create(tempd)
exportClass(accmae, dir = tempd, fmt = "csv", ext = ".csv")## Writing about 7 files to disk...## [1] "/tmp/RtmpcgoeZX/ACCMAE/accmae_META_0.csv"
## [2] "/tmp/RtmpcgoeZX/ACCMAE/accmae_META_1.csv"
## [3] "/tmp/RtmpcgoeZX/ACCMAE/accmae_ACC_CNASNP-20160128.csv"
## [4] "/tmp/RtmpcgoeZX/ACCMAE/accmae_ACC_CNVSNP-20160128.csv"
## [5] "/tmp/RtmpcgoeZX/ACCMAE/accmae_ACC_Mutation-20160128.csv"
## [6] "/tmp/RtmpcgoeZX/ACCMAE/accmae_colData.csv"
## [7] "/tmp/RtmpcgoeZX/ACCMAE/accmae_sampleMap.csv"This works for all data classes stored (e.g., RaggedExperiment, HDF5Matrix,
SummarizedExperiment) in the MultiAssayExperiment via the assays method
which converts classes to matrix format (using individual assay methods).
