A function to assist with getting valid EML unit ids (see examples). Warning: ensure returned unit is equivalent to input unit (for example "pH" will return "picohenry" which may or may not be equivalent to the input unit "pH").
Usage
get_unit_id(input_units, eml_version = emld::eml_version())Arguments
- input_units
(character|vector) input units that needs valid EML unit ids
- eml_version
(character) the eml schema version desired (there is a change in the way eml units are named from eml-2.1.1 to eml-2.2.0)
Value
(character) A valid EML unit id. If no valid EML unit id can be found, the function will output a warning, along with a preformatted custom unit id.
Examples
if (FALSE) {
# The following all return the same id
get_unit_id("kilometersPerSquareSecond")
get_unit_id("kilometerPerSecondSquared")
get_unit_id("Kilometers per seconds squared")
get_unit_id("km/s^2")
get_unit_id("km s-2")
get_unit_id("s-2 / kilometers-1") # this works but is not advised
}
