Environmental and Space Electromagnetics between . objects in R and external formats, including the ones typically used by GIS. In this chapter, we first show how coordinate reference systems can be handled portably for import and export, going on to transfer vector and raster data, and finally consider ways of linking R and GIS more clos

The Shuttle Electrodynamic Tether MissionChap. 2. We first consider the question of the spatial support of observations, going on to look at overlay and sampling methods for a range of classes of spatial objects. Following this, we cover combining the data stored in the data slot of Spatial*DataFrame objects with additional data stored as

Environmental and Space Electromagneticsten happens that customised classes would suit the actual data coming from the instruments better. Since S4 classes have mechanisms for inheritance, it may be attractive to build on the . classes, so as to utilise their methods where appropriate. Here, we demonstrate a range of different settings in

High Voltage Technology in Spaceatial distribution (and its causes) of a tree species for which the locations have been obtained within a study area. Furthermore, if two or more species have been recorded, it may also be of interest to assess whether these species are equally distributed or competition exists between them. Other f

The observed data are frequently aggregations within the boundaries, such as population counts. The areal entities may themselves constitute the units of observation, for example
