Class RFsp

Description

"RFsp" is a virtual class which contains the four classes RFspatialGridDataFrame (data on a full grid and space-time-dimension > 2), RFspatialPointsDataFrame (data not on a grid and space-time-dimension > 2), RFgridDataFrame (data on a full grid and space-time-dimension = 1), RFpointsDataFrame (data not on a grid spaced and space-time-dimension = 1)

The first two class subclasses are summarized in "RFspatialDataFrame" whilst the latter two are summarized in "RFdataFrame".

Objects from the Class

are never to be generated; only derived classes can be meaningful

Methods

summary

signature(obj = "RFsp"): returns a summary of the object; uses or imitates summary method of class Spatial from the sp-package

dimensions

signature(obj = "RFsp"): retrieves the number of spatial or spatio-temporal dimensions spanned

isGridded

signature(obj = "RFsp"): logical, tells whether the data is on a regular spatial grid

RFspDataFrame2dataArray

signature(obj = "RFsp"): transforms RFsp objects to array

RFspDataFrame2conventional

signature(obj = "RFsp"): transforms RFsp objects to a list with additional information

[

signature(obj = "RFsp"): selects columns of the data-slot, while all other slots are kept unmodified

[<-

signature(obj = "RFsp"): replaces columns of the data-slot, while all other slots are kept unmodified

variance

signature(object = "RFsp"): returns the kriging variance if available

Warning

this class is not useful in itself, but the above mentioned classes in this package derive from it
