Hello,

I have a question which should be very simple. I have a list of long-lat
coordinates of 196 sites and I need to calculate the great circle distance
(in miles?) between all of them. I can't find the right function though... I
need this in order to calculate the quartiles of the distances between all
the regions and set a cut-off distance to create a neighbor list. I have
tried the "dist" function but the output doesn't seem to be what I expected,
because I cannot recognize the numbers I get as the distance between the
sites: they're too low (max 44.51000, but the sites are the European
regional capitals...).

Does anyone have a hint on this?

Thank you very much,
Annachiara Saguatti
