arrivals_by_machinery | R Documentation |
Estimates pest arrivals through imported machinery as a function of population density.
arrivals_by_machinery( pop_density, leakage_rate, establishment_rate, outfile, return_rast = FALSE, overwrite = FALSE )
pop_density |
A |
leakage_rate |
Numeric vector of 2 values, giving the lower and upper bounds of a 95% CI for leakage rate (the number of pest leakage events in a random year). |
establishment_rate |
Numeric vector of 2 values, giving the lower and upper bounds of a 95% CI for establishment rate (the rate of survival, to establishment, for leakage events). |
outfile |
Character. Output raster file path. If |
return_rast |
Logical. Should the raster object be returned to R?
Ignored if |
overwrite |
Logical. If |
This pathway is used under the assumption that the vast majority of imported machinery comprises new and used motor vehicles.
If outfile
is specified, the resulting raster (multiband if
probability
has length > 1) is saved as a tiff at that path. If
return_rast
is TRUE
or outfile
is not specified the
resulting raster object is returned, otherwise NULL
is returned
invisibly.
