CompactStratificationPriorPoints-class {spcosa} | R Documentation |
A class for storing a stratification with compact strata, given prior sampling locations.
Objects can be created by calls of the form new("CompactStratificationPriorPoints", cells, stratumId, centroids, mssd, priorPoints)
. However, objects are usually created by calling stratify
.
priorPoints
:"SpatialPoints"
, containing the coordinates of the existing locations.cells
:"SpatialPixels"
, representing the area to be partitioned.stratumId
:"integer"
, indicating to which stratum each cell in cells
belong.centroids
:"SpatialPoints"
, representing the centers of gravity of each stratum.mssd
:"numeric"
, representing the mean squared shortest distance.
Class "CompactStratification"
, directly.
Class "Stratification"
, by class "CompactStratification", distance 2.
signature(x = "CompactStratificationPriorPoints", n = "missing", type = "missing")
: returns the centers of gravity of strata without prior points in addition to the prior points.Dennis J. J. Walvoort dennis.walvoort@wur.nl, D.J. Brus, J.J. de Gruijter
