R Documentation
Determine whether two units may be converted between each other
Description
This function takes udunits compatible strings and determines whether
or not it is possible to convert between them.
Usage
ud.are.convertible(u1, u2)
Arguments
u1
A character string which is parseable into a udunits compatible unit.
u2
Another character string which is also parseable into a udunits compatible unit.
Details
Even if two units are parseable and recognized by the udunits library,
it may or may not be possible to convert from one to another. For
example, it makes sense to convert from celsius to kelvin, however not
from celsius to kilograms. This function allows the user to check if
two units are of the same system and if there exists a defined conversion between
the two.
Value
Returns a logical: True if the units can be converted between
each other, False if either of the arguments is not parseable
by udunits, or if no conversion is possible.
