Subsetting a MultiAssayExperiment by the j index can yield a call
to either subsetByColData
or subsetByColumn
. For vector inputs,
the subset will be applied to the colData
rows. For List
-type
inputs, the List will be applied to each of the elements in the
ExperimentList
.
The order of the subsetting elements in the
List
must match that of the ExperimentList
in the
MultiAssayExperiment
.
subsetBycolData: Select biological units by vector input types
subsetByColumn: Select observations by assay or for each assay
subsetByRow: Select rows by assay or for each assay
subsetByAssay: Select experiments
subsetBy*
operations are endomorphic and return either
MultiAssayExperiment
or ExperimentList
depending on the
input.
## Load the example MultiAssayExperiment
example("MultiAssayExperiment")
## Using experiment names
subsetByAssay(mae, "Affy")
## Using numeric indices
subsetByAssay(mae, 1:2)
## Using a logical vector
subsetByAssay(mae, c(TRUE, FALSE, TRUE))
## Subset by character vector (Jack)
subsetByColData(mae, "Jack")
## Subset by numeric index of colData rows (Jack and Bob)
subsetByColData(mae, c(1, 3))
## Subset by logical indicator of colData rows (Jack and Jill)
subsetByColData(mae, c(TRUE, TRUE, FALSE, FALSE))
subsetByColumn(mae, list(Affy = 1:2,
Methyl450k = c(3,5,2), RNASeqGene = 2:4, GISTIC = 1))
subsetWith <- S4Vectors::mendoapply(`[`, colnames(mae),
MoreArgs = list(1:2))
subsetByColumn(mae, subsetWith)
## Use a GRanges object to subset rows where ranged data present
egr <- GenomicRanges::GRanges(seqnames = "chr2",
IRanges::IRanges(start = 11, end = 13), strand = "-")
subsetByRow(mae, egr)
## Use a logical vector (recycling used)
subsetByRow(mae, c(TRUE, FALSE))
## Use a character vector
subsetByRow(mae, "ENST00000355076")
