extractSpatialDataFrame: Extract some values of Simulations to a SpatialDataFrame with...

In sensors4plumes: Test and Optimise Sampling Designs Based on Plume Simulations

Description

Turn some of the values of a Simulations object into a SpatialDataFrame, keeping the spatial reference.

Usage

extractSpatialDataFrame(obj, kinds = 1:nlayers(obj@values),
  plumes = 1:ncol(obj@values), chunksize = 1e+7)

Arguments

obj	Simulations object
kinds	integer: values of which layers (kind) of the values to extract
plumes	integer: values of which plume to extract
chunksize	limit of cells to extract, if selected kinds and plumes exceed this limit, only the first are extracted (with warning)

Details

This function can be used to extract the maps in Simulations objects: the values are assigned to the spatial properties, for plotting, combining it with other spatial data etc. As the size of all values may exceed the memory, it may extract only the first of the kinds and plumes.

Value

A SpatialDataFrame with the same spatial reference as the locations of the obj with the values of the chosen plume and layer as attribute.
