get_unitList {EML}

get_unitList

Description

get_unitList

Usage

get_unitList(x = NULL)

Arguments

x

an emld object

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()'.

Value

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.

Examples

# Read in additional units defined in a EML file

f <- system.file("tests", emld::eml_version(),
  "eml-datasetWithUnits.xml",
  package = "emld"
)
eml <- read_eml(f)
unitList <- get_unitList(eml)

## Read in the definitions of standard units:
