Hi all,

My question is really more statistical theory than about R, however I would
greatly appreciate if someone can provide guidance.
I am trying to measure distance between points given j number of variables,
a subset of which is latitude and longitude. To make the distance
scale-invariant, I use Mahalanobis distance. Is this a correct way of
measuring distance in j-dimensional space given that latitude and longitude
should be taken jointly?

Cheers,
Michael
