Three of them (the largest ones) will be my main polygons and the rest of them must become holes inside one of the three major areas. I’m able to transform all the closed lines into SpatialPolygons and even create shapefiles with them, but how can I modify the “hole” slot of the smaller polygons so I can keep them transparent when overlaying another map (those holes will overlay islands of a raster image)?<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>Thank you for the attention and help.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Regards.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:7.5pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'>-------------------------------------------------------------------<o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:8.0pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'>MSc. <a href="mailto:r.aluizio@gmail.com"><span style='color:blue'>Rodrigo Aluizio</span></a><o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:7.5pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'>Centro de Estudos do Mar/UFPR</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'><br></span><span style='font-size:7.5pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'>Laboratório de Foraminíferos e Micropaleontologia Ambiental</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'><br></span><span style='font-size:7.5pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'>Avenida Beira Mar s/n - CEP 83255-971</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'><br></span><span style='font-size:7.5pt;font-family:"Tahoma","sans-serif";mso-fareast-language:PT-BR'>Pontal do Paraná - PR - Brazil<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
