In kstierhoff/atm: Functions Used for the Analysis of Acoustic-Trawl Method (ATM) Survey Data

Calculate point estimate of species biomass

Description

Calculate point estimate of species biomass

Usage

estimate_point(df, stratum.area, species)

Arguments

df	A data frame containing total backscatter from all CPS (cps.nasc), acoustic proportions (prop.spp), and weight-specific backscattering cross sections (sigmawg.spp) in a given stratum
stratum.area	A vector containing stratum areas (in square meters).
species	A vector containing the species' scientific name (Clupea pallasii, Engraulis mordax, Sardinops sagax, Scomber japonicus, or Trachurus symmetricus).

Value

A data frame with the stratum areas and point estimates of total biomass.

Examples

estimate_point(df, stratum.area, "Engraulis mordax")
