R is a language for statistical computing. As such it has a strong capacity for storing, handling and manipulating numerical or categorical data. R has dedicated data structures and methods for specific kinds of data, now including spatial data. Although one could argue that spatial data are just regular data with coordinates, life is much easier when they are structured. A large number of packages provide spatial statistical methods or interfaces to GIS, and many of them provide data structures and e.g. plotting methods for spatial data.

There are several reasons for providing this package of classes for spatial data:
