An S4 class to represent Relative Radius as an image. Use the helper function makeRimage to generate a new RelativeRadiusImage.

raster package offer a wide range of functionalities to manipulate raster files efficiently. It uses georeferenced raster because was designed with a field-based conception of the geographical reality (Galton, 2011). To manipulate such data, raster package defines "S4 classes" grouped in the Raster family that has a complex hierarchical structure of inheritance. These classes have slots that help to precisely locate each cell over the earth because they were designed to represent georeferenced raster. RelativeRadiusImage was built on top of RasterLayer to take advantage of raster package functionality. However, RelativeRadiusImage requires raster implementation but not georeference. That is why some inherited slots are meaningless for these class.

diameter: integer.
...: Inherited from RasterLayer.
