retrieve bbox from spatial data
retrieves spatial bounding box from spatial data
bbox(obj)
obj |
object deriving from class "Spatial", or one of classes: "Line", "Lines", "Polygon" or "Polygons", or ANY, which requires obj to be an array with at least two columns |
two-column matrix; the first column has the minimum, the second the maximum values; rows represent the spatial dimensions
object deriving from class "Spatial"
an array with at least two columns
object deriving from class "Line"
object deriving from class "Lines"
object deriving from class "Polygon"
object deriving from class "Polygons"
# just 9 points on a grid: x <- c(1,1,1,2,2,2,3,3,3) y <- c(1,2,3,1,2,3,1,2,3) xy <- cbind(x,y) S <- SpatialPoints(xy) bbox(S) # data.frame data(meuse.grid) coordinates(meuse.grid) <- ~x+y gridded(meuse.grid) <- TRUE bbox(meuse.grid)
