This function converts between numerical units.
It works similar to the iconv function:
You provide vector x and a from and a to unit name
and the function converts.
This is an internal class. It administers the unitsets
used by the uconv method. One instance, usually
the only one, is created at startup.
Internal function to create an UnitSetManager object.
Usage
uconv(x, from, to, uset = NULL)
unitsetmanager()
Arguments
x
numerical vector
from
character, unit to convert from.
to
character, unit to convert to
uset
optional, character, unit set to use.
Details
Additionally, you may provide a unitset name. Here, the
analogy to iconv ceases. Think of unitset as a
dimension of units, or a context for units. Predefined
unitsets are "Length", "Mass", "Energy", and "Temperature".
It is recommened to provide the unitset name.
A list of available unitsets and the units defined by them
can be obtained with uconvlist().
This is a proof of concept for the datamart function.
