Consider:

,(30 12, 50 5, 65 7))")
mls is, as expected, a SpatialLines object, and
plotting it shows that indeed it has three individual
lines. My question is: is there some way to subset this
object so as to obtain a smaller SpatialLines object?
(say, by excluding the second Line)?
They're considered as a single line; try length(mls). If somebody comes up with a simple function to do this, and a similar thing for polygons, and we can agree on a name for such a thing (unfold?) I'm willing to consider it for sp. Or is it already somewhere?
