A class for storing composites obtained by random sampling.
Objects can be created by calls of the form new("SamplingPatternRandomComposite", ...). However, objects are usually created by calling spsample.
Class "'>SamplingPatternRandom", directly.
Class "'>SamplingPattern", by class "SamplingPatternRandom", distance 2.
signature(from = "SamplingPatternRandomComposite", to = "data.frame"): coerces to "data.frame".
signature(from = "SamplingPatternRandomComposite", to = "SpatialPointsDataFrame"): coerces to "'>SpatialPointsDataFrame".
signature(statistic = "SamplingVariance", stratification = "CompactStratificationEqualArea", samplingPattern = "SamplingPatternRandomComposite", data = "data.frame"): estimates the sampling variance. See "'>SamplingVariance" for more details.
signature(statistic = "SpatialMean", stratification = "CompactStratificationEqualArea", samplingPattern = "SamplingPatternRandomComposite", data = "data.frame"): estimates the spatial mean. See "'>SpatialMean" for more details.
signature(object = "SamplingPatternRandomComposite"): returns the sample size per stratum.
signature(x = "CompactStratification", y = "SamplingPatternRandomComposite"): plots sampling pattern y on top of stratification x.
signature(x = "SamplingPatternRandomComposite", y = "missing"): plots sampling pattern x.
