View source: R/emeScheme_extract.R

One emeScheme object can contain metadata for multiple dataFiles. For archiving, these should be split into single emeScheme objects, one for each DataFileNameMetaData$dataFileName. This function extracts the metadasta from one dataFile in an emeScheme object and returns an emeScheme object.

1	emeScheme_extract(dataFile, x)

`dataFile`	name of dataFile whose metadata will be extracted from `x`. Has to be an exact match, no wildcards are expanded.
`x`	`emeScheme` object from which to extract the metadata

The filtering is done as followed:

DataFileMetaDFata: DataFileMetaData$dataFileName == dataFile
Treatment: Treatment$parameter %in% DataFileMetaData$mappingColumn and DataFileMetaData$columnData == "Treatment"
Measurement: Measurement$name %in% DataFileMetaData$mappingColumn and DataFileMetaData$columnData == "Measurement"

An emeScheme object containing metadata for the data file dataFileName

emeScheme_extract("smell.csv", dmdScheme_example())
## returns the emeScheme data for the data file 'smell.csv'

emeScheme_extract("DoesNotExist", dmdScheme_example())
## returns an empty emeScheme
