Here I use the solution of Duncan Murdoch, it is almost that I want, now I try
to resolve the default of his methods, e.g. I don't want smooth the contour (
the border) of my raster.
Thank for your help :-))
(Sorry for the spam, I have f
constrains, and I
don't see how gPolygon can help me (in it doc, I have seen this function cut
polygon in a set of subpolygon.

I think it is a very good idea, thank a lot, I will try this!

##smooth contour
contours <- contourLines(V2b,levels=paliers)

The problem is the curve of my contour is so linear, and I would like a more
continuous contour. I use the function fitted.contour to draw my map.
Thanks,
