conventional2RFspDataFrame: Coercion to class 'RFsp' objects

Description

Generate an object of class RFsp from conventional objects

Usage

conventional2RFspDataFrame(data, coords=NULL, gridTopology=NULL, n=1,
                           vdim=1, T=NULL, vdim_close_together)

Arguments

data

array; of dimension c(vdim, space-time-dim, n); contains the values of the random fields

coords

matrix of coordinates

gridTopology

3-row-matrix or of class GridTopology; specifies the grid vectors; either coords or gridTopology must be NULL

n

number of iid copies of the random fields, default is 1

vdim

number of dimensions of the values of the random field, default is 1

T

time component if any. The length of the temporal grid is needed by as.array if the spatial locations are randomly scattered.

vdim_close_together

logical. Currently only vdim_close_together=FALSE is coded. In this case the dimensions of the data follow the order locations, multivariate, repeated. Otherwise multivariate, locations, repeated.

Value

• object of class RFspatialGridDataFrame, RFspatialPointsDataFrame, RFgridDataFrame or RFpointsDataFrame

Examples

RFoptions(seed=0) ## *ANY* simulation will have the random seed 0; set
##                   RFoptions(seed=NA) to make them all random again
x <- 1:20
z <- RFsimulate(RMexp(), x, spConform=FALSE)
z2 <- conventional2RFspDataFrame(z, coord=x)
Print(z, z2)
