Hello! I have some troubles plotting shapefiles with ggplot2. First of all, I plotted a polygon (shapefile) without problems, and the same time, I want to plot lines (shapefile) inside the polygon but something wrong happened whit the lines because appears some small polygons (I showed it in the image). Also, I am trying to plot some points (shapefile) inside the same graphic but I can't. Finally, I don't know if somebody can help me with these problems and adding a legend with these shapefiles (polygon, points and lines). Thank you very much.
Regards,
Diego
