I'm working with R and various shapefiles created by the OpenStreetMap
project. Those shapefiles (the roads in particular) are quite big.
How can I crop (or "trim", or "prune" those objects -- once in a
SpatialLineDataFrame -- if I need to work not on a national level but
on a municipal level ?
Is it possible to create a subset of a smaller zone ?

r2 49.493613 51.505419
