<p class=MsoNormal><span lang=EN-US>Hi Sig list, I’m really new
representing spatial data, but I’m already able to create excellent maps
using sp, maptools and mapdata packages. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Anyway, I have a SpatialLines object (attached)
which I would like to “close” and turn it into a SpatialPolygon, so
I can fill it with a color. The object already posses some closed lines (islands)
but the entire area is wide open. To make things easier it could be closed at
the ocean side (right side, if plotted), so there will be no need to deal with
the open and closed areas. This “closure” may be done as the coast
line was and hypotenuse of a rectangular triangle.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Is there a way to do so? I was looking for
something similar to that in the R site search, but I didn’t found a
total match with my issue, or maybe I’m too new to that, so I wasn’t
even able to recognize a solution </span><span lang=EN-US style='font-family:

<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>

the question was already answered.<o:p></o:p></span></p>
