[R-sig-Geo] Circles as polygons?

[Pieter Botha]

Hi

I have a SpatialPointsDataFrame, originating from location readings from an Android device. These readings are received as latitude / longitude as well as an accuracy reading in meters. An csv dump of the SpatialPointsDataFrame can be downloaded here: http://www.ploemp.com/opla/statp.csv

I am interested in finding points of interest that falls within an accuracy reading for a location. The sp class only supports points, lines and polygons so I guess I will have to construct a polygon that estimates the circle formed by the location with accuracy as radius?

Any pointers here?

Thanks,
Pieter
