Has anyone got a neat way in R to handle scientific units along with numeric
vectors? e.g. in mathematica, there is a Units package to allow you to
do the following:
85 Meter/Second * 10 Second
answer: 850 Meter

Not really. There is limited support for conversions as well. I have wondered about this after addressing a similar question on Stack Overflow: http://stackoverflow.com/questions/7214781/converting-units-in-r/7215430#7215430

As a program that was originally design to symbolic algebra it is not surprising to find such methods in Mathematica. I have looked around for examples of implementations in other languages and have found them in LisP and in PERL http://www.cs.utexas.edu/users/novak/units.html http://search.cpan.org/~klortho/Physics-Unit-0.04/lib/Physics/Unit.pm
