[R-sig-Geo] How to establish location of points relative to a line

[Bjarke Christensen]

Hi,

I have a SpatialLinesDataFrame (A) and a SpatialPointsDataFrame (B). How
can I establish which points in B are to the east of a given line in A?

The problem is to figure out which persons (whose addresses are geocoded in
B) have addresses to the east of a given road (whose coordinates are given
in A).

Thanks in advance!
