as.SpatialGridDataFrame {marmap}

Convert bathymetric data to a spatial grid

Description

Transforms an object of class bathy to a SpatialGridDataFrame object.

Usage

as.SpatialGridDataFrame(bathy)

Arguments

bathy

an object of class bathy

Details

as.SpatialGridDataFrame transforms bathy objects into objects of class SpatialGridDataFrame as defined in the sp package. All methods from the sp package are thus available for bathymetric data (e.g. rotations, projections...).

Value

An object of class SpatialGridDataFrame with the same characteristics as the bathy object (same longitudinal and latitudinal ranges, same resolution).
