To return samples across studies, users will use returnSamples() along with
the sampleMetadata data.frame subset to include only desired samples and
metadata. The subset sampleMetadata data.frame will be used to get the
desired resources, mergeData will be used to merge them, and the subset
sampleMetadata data.frame will be used again to subset the
SummarizedExperiment or
TreeSummarizedExperiment
object to include only desired samples and metadata.
returnSamples(sampleMetadata, dataType, counts = FALSE, rownames = "long")the sampleMetadata data.frame subset to include
only desired samples and metadata
the data type to be returned; one of the following:
"gene_families"
"marker_abundance"
"marker_presence"
"pathway_abundance"
"pathway_coverage"
"relative_abundance"
if FALSE (the default), relative abundance proportions are
returned; if TRUE, relative abundance proportions are multiplied by read
depth and rounded to the nearest integer prior to being returned
the type of rownames to use for relative_abundance
resources, one of: "long" (the default), "short" (species name), or
"NCBI" (NCBI Taxonomy ID)
when dataType = "relative_abundance", a
TreeSummarizedExperiment
object is returned; otherwise, a SummarizedExperiment
object is returned
At present, curatedMetagenomicData resources exists only as entire studies which requires potentially getting many resources for a limited number of samples. Furthermore, because it is necessary to use mergeData internally, the same caveats detailed under Details in mergeData apply here.
