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

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

obj |
|
kinds |
integer: values of which layers (kind) of the |
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) |
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.
A SpatialDataFrame
with the same spatial reference as the locations
of the obj
with the values of the chosen plume
and layer
as attribute.
