<p class="MsoNormal"><span lang="EN-US">I have a Shapefile representing the censal sections of Spain, and my interest is creating a KML file with only 52 polygons representing the different provinces of Spain. I shall use readOGR, and my problem comes when
I have a SpatialPolygonsDataFrame object in R and I want to merge in only one polygon all the censal sections of every province. I have an attribute with the province ID defined in the same object, so it would only be aggregating the censal sections with the
same province ID, but still I don’t know how to do it.<o:p></o:p></span></p>
