window

Set a window

Description

Experimental: 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.

Currently, the window will be forced to intersect with the extent of the SpatRaster. It is envisioned that in future versions, 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
