[R-sig-Geo] Determine if a line segment intersects a polygon

[Waichler, Scott R]

I am looking for a method that would determine whether any part of a
line segment defined by (x0, y0) and (x1, y1) intersects a given polygon
(true or false).  I don't have any other geospatial needs here, so if a
solution exists using base R that would be great.

Thanks,
