[R-sig-Geo] A question re: tripack / voronoi cell area units

Greetings:

I've checked the tripack documentation for an answer to this question:
How to determine the units for areas calculated for voronoi mosaic cells 
(by the cells method)
in the tripack package?

I assume that they are related to the units of the $x and $y coordinates 
input to the voronoi.mosaic()
method. For example, if the coordinates are expressed in decimal 
degrees, then the cell side lengths
are also expressed in decimal degrees and the cell areas would be in 
units of decimal degrees ** 2.

Can someone affirm or correct this assumption?

Thanks,
Rick R
