a unitList object. Usually found in eml@additionalMetadata[[1]]@metadata, see details |
If no unitList is provided, the function reads in the eml-unitDictionary defining all standard units and unitTypes. This provides a convenient way to look up standard units and their EML-recognized names when defining metadata, e.g. in the table passed to 'set_attributes()'.
a list with two data.frames: "units", a table defining unit names, types, and conversions to SI, and "unitTypes", defining the type of unit. For instance, the unit table could define "Hertz" as a unit of unitType frequency, and the unitType define frequency as a type whose dimension is 1/time.
# Read in additional units defined in a EML file
f <- system.file("xsd/test/eml-datasetWithUnits.xml", package = "EML")
eml <- read_eml(f)
unitList <- get_unitList(eml@additionalMetadata[[1]]@metadata)
