Dear Ahmed,
A SpatialPolygons object is more complex than just a set of coordinates. I
suggest that you read the helpfile of SpatialPolygonsDataFrame. The example
in the helpfile for the SpatialPolygonsDataFrame class should be clear
enough.

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
