window: Set a window

In terra: Spatial Data Analysis

Set a window

Description

Assign a window (area of interest) to a SpatRaster with a SpatExtent, or set it to NULL to remove the window. This is similar to crop without actually creating a new dataset.

The window is intersect with the extent of the SpatRaster. It is envisioned that in a future version, the window may also go outside these boundaries.

Usage

## S4 replacement method for signature 'SpatRaster'
window(x)<-value

## S4 method for signature 'SpatRaster'
window(x)

Arguments

x	SpatRaster
value	SpatExtent

Value

none for window<- and logical for window

Examples

 
f <- system.file("ex/elev.tif", package="terra") 
r <- rast(f)
global(r, "mean", na.rm=TRUE)
e <- ext(c(5.9, 6,49.95, 50))

window(r) <- e
global(r, "mean", na.rm=TRUE)
r

x <- rast(f)
xe <- crop(x, e)
global(xe, "mean", na.rm=TRUE)

b <- c(xe, r)
window(b)
b

window(r) <- NULL
r
