R Documentation

Create, get or set a SpatExtent

Description

Get a SpatExtent of a SpatRaster, or coordinates from such an object. Or create a SpatExtent from a vector (length=4; order= xmin, xmax, ymin, ymax)

See set.ext to set the extent in place.

Usage

## S4 method for signature 'SpatRaster'
ext(x, cells=NULL)

## S4 method for signature 'SpatVector'
ext(x)

## S4 method for signature 'numeric'
ext(x, ...)

## S4 replacement method for signature 'SpatRaster,SpatExtent'
ext(x)<-value

## S4 replacement method for signature 'SpatRaster,numeric'
ext(x)<-value

## S4 method for signature 'SpatExtent'
x$name

## S4 replacement method for signature 'SpatExtent'
x$name<-value

Arguments

x	SpatRaster
cells	postive integer (cell) numbers to subset the extent to area covered by these cells
value	SpatExtent, or numeric vector of lenght four (xmin, xmax, ymin, ymax), or a single number with the $ method
name	charcter, one of xmin, xmax, ymin, or ymax
...	if x is a single numeric value, additional numeric values for xmax, ymin, and ymax

Value

SpatExtent
