| kml-methods {plotKML} | R Documentation |
Writes any Spatial* object (from the sp package) or Raster* object (from the raster package) to a KML file via the plotKML.fileIO environment. Various aesthetics parameters can be set via colour, alpha, size, shape arguments. Their availability depends on the class of the object to plot.
## S4 method for signature 'Raster' kml(obj, folder.name, file.name, kmz, ...) ## S4 method for signature 'Spatial' kml(obj, folder.name, file.name, kmz, ...) ## S4 method for signature 'STIDF' kml(obj, folder.name, file.name, kmz, ...) ## S4 method for signature 'SoilProfileCollection' kml(obj, folder.name, file.name, kmz, ...) ## S4 method for signature 'SpatialPhotoOverlay' kml(obj, folder.name, file.name, kmz, ...)

folder.name |

additional aesthetics arguments (see details below) |
To kml you can also pass folder.name, file.name (output file name *.kml), overwrite (logical; overwrites the existing file) and kmz (logical; specifies whether to compress the kml file) arguments. Gridded objects (objects of class "SpatialGridDataFrame" or "RasterLayer" require at least one aesthetics parameter to run, usually the colour.)
A KML file. By default parses the object name and adds a ".kml" extension.
