I am interested in plotting variable-width lines, based on
NumberOfTrips, between point pairs (OriginLongitude,OriginLatitude)
and (DestinationLongitude,DestinationLatititude), e.g. a flow map
between the ports. At some point, I may wish to add an underlay base
map (say counties in the US), but that is not critical at this time.
There seem to be many packages in R that deal with spatial data (sp,
