extent-scidbst-methods: Gets and sets the spatial extent of a scidbst array

In flahn/scidbst: Spatio Temporal Extension for SciDB (scidbst)

Description

This function let you retrieve the spatial extent as a Extent-class object. With the additional functions xmin, xmax, ymin and ymax particular information about the extent can be retrieved directly from the scidbst object. Using the "<-" operator a spatial extent can be set for a scidb array or it replaces the spatial extent of a scidbst array with an Extent-class object.

Usage

## S4 method for signature 'scidbst'
extent(x)

## S4 replacement method for signature 'scidbst,Extent'
extent(x) <- value

## S4 replacement method for signature 'scidb,Extent'
extent(x) <- value

## S4 method for signature 'scidbst'
xmin(x)

## S4 method for signature 'scidbst'
ymin(x)

## S4 method for signature 'scidbst'
xmax(x)

## S4 method for signature 'scidbst'
ymax(x)

Arguments

x	scidb or scidbst array
value	An object of class Extent

Value

Extent-class object or scidbst object

Note

Setting the extent with extent<- has an informative meaning. By setting the extent on a scidbst object the extent will be replaced, but NO cropping or subsetting will be performed.
