  DateFile = paste0(getwd(), "/"),
  standardize_fields = FALSE
)

Arguments

Sim_Settings	an optional tagged list for specifying input parameters (see function code to determine settings)
Extrapolation_List	the output from make_extrapolation_info
Data_Geostat	A data frame with column headers c('Lon','Lat','Year','Vessel','AreaSwept_km2') containing sample design to mimic
standardize_fields	Boolean, whether to ensure that random fields have sample mean and standard deviation equal to their inputted values

Value
