Calculate expanded annual total catch size compositions by crab fishery, area, year, sex and shell condition

Description

Function to calculate expanded annual total catch size compositions by crab fishery, area, year, sex and shell condition.

Usage

adfg.calcTotalCatchZCs(
  tblTotAB,
  tblTotZCsRaw,
  cutpts = seq(from = 5, to = 185, by = 5),
  truncate.low = TRUE,
  truncate.high = FALSE
)

Arguments

tblTotAB	: dataframe with total catch abundance and biomass by fishery, area, year, sex, and shell condition
tblTotZCsRaw	: data.frame from call to function adfgRead_MPD()
cutpts	: cutpts for bins
truncate.low	: flag to exclude crab with sizes less than minimum cutpt (default=TRUE)
truncate.high	: flag to exclude crab with sizes greater than maximum cutpt (default=FALSE)

Details

Uses sqldf::sqldf() and reshape2::dcast(). tblTotZCsRaw should have columns "fishery", "area", "year", "sex", "maturity", "shell condition", "size" and "count".

Value

a dataframe with columns

• fishery

• area

• sex

• shell condition

• year

• size

• abundance (in thousands of crab)
