gg is a generic function for generating geomes from various kinds of spatial objects, e.g. Spatial* data, meshes, Raster objects and inla/inlabru predictions. The function invokes particular methods which depend on the class of the first argument.


gg(data, ...)



an object for which to generate a geom.


Arguments passed on to the geom method.


The form of the value returned by gg depends on the class of its argument. See the documentation of the particular methods for details of what is produced by that method.
