A data frame with 32 x 31 flow measurements, 992 rows, and seven columns:

Orig: factor, the origin district.
Dest: factor, the destination district.
DistEuc: numeric, Euclidean distance between the districts.
DistRd: numeric, road distance between districts.
O.GRP: numeric, gross regional product of the origin district, in Austrian schillings.
D.GRP: numeric, gross regional product of the destination district, in Austrian schillings.
Flow: the “amount” of phone calls from the origin district to the destination district, in erlang units (number of phone calls, including faxes, times the average length of the call divided by the duration of the measurement period).
