Spatial element extent

Usage

# S4 method for class 'SpatialData'
extent(x, i = 1)

# S4 method for class 'SpatialDataArray'
extent(x, i = 1)

# S4 method for class 'SpatialDataFrame'
extent(x, i = 1)

Arguments

x: a SpatialData element (any but table).
i: scalar integer or string; target coordinate space.

Value

Length-2 list with numeric x and y ranges.

Examples

x <- file.path("extdata", "blobs.zarr")
x <- system.file(x, package="SpatialData")
x <- readSpatialData(x, tables=FALSE)
