xmin {terra} | R Documentation

## Get or set single values of an extent

### Description

Get or set single values of an extent. Values can be set for a SpatExtent or SpatRaster, but not for a SpatVector)

### Usage

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

### Arguments

`x` | SpatRaster, SpatExtent, or SpatVector
`value` | numeric

### Value

SpatExtent or numeric coordinate

### Examples

    r <- rast()
    ext(r)
    ext(c(0, 20, 0, 20))

    xmin(r)
