udunits2 utilities

Description

Some udunits2 utilities are exposed to the user. These functions are useful for checking whether units are convertible or converting between units without having to create units objects.

Usage

ud_are_convertible(from, to, ...)

ud_convert(x, from, to)

Arguments

from	character or object of class symbolic_units, for the symbol of the original unit.
to	character or object of class symbolic_units, for the symbol of the unit to convert.
...	unused.
x	numeric vector

Value

ud_are_convertible returns TRUE if both units exist and are convertible, FALSE otherwise.

ud_convert returns a numeric vector with x converted to new unit.

Examples

ud_are_convertible("m", "km")
ud_convert(100, "m", "km")

a <- set_units(1:3, m/s)
ud_are_convertible(units(a), "km/h")
ud_convert(1:3, units(a), "km/h")

ud_are_convertible("degF", "degC")
ud_convert(32, "degF", "degC")
