Distribution of emissions by area

Calculate the spatial distribution by a raster kasked by shape/model grid information.

areaSource(s, r, grid = NA, name = "", as_frac = F, verbose = T)

Arguments

s	input shape object
r	input raster object
grid	grid with the output format
name	area name
as_frac	return a fraction instead of a raster
verbose	display additional data

Format

a raster
