SamplingPatternRandomSamplingUnits-class {spcosa}

Class "SamplingPatternRandomSamplingUnits"

Description

A class for storing sampling units obtained by random sampling.

Objects from the Class

Objects can be created by calls of the form new("SamplingPatternRandomSamplingUnits", ...). However, objects are usually created by calling spsample.

Slots

sample:

Object of class "SpatialPoints", containing the sampling locations.

Extends

Class "SamplingPatternRandom", directly. Class "SamplingPattern", by class "SamplingPatternRandom", distance 2.

Methods

estimate

signature(statistic = "SamplingVariance", stratification = "CompactStratification", samplingPattern = "SamplingPatternRandomSamplingUnits", data = "data.frame"): estimates the sampling variance. See "SamplingVariance" for more details.

estimate

signature(statistic = "SpatialCumulativeDistributionFunction", stratification = "CompactStratification", samplingPattern = "SamplingPatternRandomSamplingUnits", data = "data.frame"): estimates the spatial cumulative distribution function (SCDF). See "SamplingPatternRandomSamplingUnits" for more details.

estimate

signature(statistic = "SpatialMean", stratification = "CompactStratification", samplingPattern = "SamplingPatternRandomSamplingUnits", data = "data.frame"): estimates the spatial mean. See "SpatialMean" for more details.

estimate

signature(statistic = "SpatialVariance", stratification = "CompactStratification", samplingPattern = "SamplingPatternRandomSamplingUnits", data = "data.frame"): estimates the spatial variance. See "SpatialVariance" for more details.

estimate

signature(statistic = "StandardError", stratification = "CompactStratification", samplingPattern = "SamplingPatternRandomSamplingUnits", data = "data.frame"): estimates the standard error of the spatial mean. See "StandardError" for more details.

estimate

signature(statistic = "character", stratification = "CompactStratification", samplingPattern = "SamplingPatternRandomSamplingUnits", data = "data.frame"): estimates statistic, i.e., "spatial mean", "spatial variance", "sampling variance", "standard error", SCDF.
