R: Set a window

window {terra} | R Documentation

## 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`

### See Also

`crop`, `extend`

### 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
