Make Map or Timeseries of Total Species-Specific Exposure — make_total

Uses the logic rule from CVA1.0 to combine variable-specific exposures to create a total exposure map or timeseries

Usage

make_total_exposure(
  type,
  variable_exposure,
  count_all,
  weights,
  weight_threshold
)

Arguments

type: designates desired output, must equal 'map' or 'timeseries'
variable_exposure: If type == 'map', a rasterStack output from make_variable_exposure(type == 'map'). If type == 'timeseries', the matrix output from make_variable_exposure(type == 'timeseries').
count_all: TRUE/FALSE to use weights and wThreshold to subset variables to only important variables
weights: output from combine_weights - a vector of variable weights in ensemble SDM
weight_threshold: numeric value used to subset weights, variables with weights less to or equal to this value will be excluded from total exposure calculation

Value

If type == 'map', the output is a raster representing total exposure across space. If type == 'timeseries', the output is a vector representing total exposure across time.
