as.sts {hero}

Convert object to sts class

Description

Convert a numeric three-dimensional array or two-dimensional matrix-like object to an sts (spatial time series) object. If x is a three-dimensional array, the first two dimensions are assumed to relate to gridded spatial positions. If x has only two dimensions, each row is a time series for a specific location. Each column is a realization of a geostatistical process at a specific time.

Usage

as.sts(x)

sts(x)

as_sts(x)

Arguments

x

A matrix-like object with 2 dimensions or an array with 3 dimensions.

Details

This method has been tested with objects of class matrix, data.frame, array, and Matrix-class. It should be possible for x to have a different class as long as the object has a loaded as.matrix method, which is used in this function.

Value

An sts object.

Examples

# 3d array to sts
sts = as.sts(tasmax)
class(sts)

# extract a subset of tasmax to produce an sts
x = matrix(c(tasmax[50:60, 50:60, ]), ncol = 30)
sts = as.sts(x)
class(sts)

sts = as.sts(as.array(x))
class(sts)

sts = as.sts(Matrix::Matrix(x))
class(sts)

sts = as.sts(as.data.frame(x))
class(sts)
