Get or set single values of an extent

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

Examples

r <- rast()
ext(r)
#> SpatExtent : -180, 180, -90, 90 (xmin, xmax, ymin, ymax)
ext(c(0, 20, 0, 20))
#> SpatExtent : 0, 20, 0, 20 (xmin, xmax, ymin, ymax)

xmin(r)
#> [1] -180
xmin(r) <- 0
xmin(r)
#> [1] 0
