[R-sig-Geo] readOGR cannot open .shp file

[MacQueen, Don]

What does
  list.files()
show ‹ after having set the working directory, of course.

Have you successfully loaded other shape files before, or is this the
first time?

Do any of the shape file examples in ?readOGR succeed?

Is the shape file complete? That is, are the .prj, .dbf, .shx, and so on,
files there?
(I¹m not sure what the complete required list is)
