SepVPA
in package in Package ‘FLAssess’. Requires an object of class

SepVPA<-function(stock, control=FLSepVPA.control(), ref.harvest="missing", fratio="missing", fit.plusgroup=TRUE, desc="",...)
, where
stock

, control
is of type FLSepVPA.control()
, ref.harvest
and fratio
are numeric and fit.plusgroup
is Boolean.
# Example based on ple4 dataset data(ple4) # Set up stock with correct dimensions my.stock <- FLStock(catch.n(ple4)) my.stock@range["plusgroup"] <- 15 #load catch data and mortality my.stock@catch.n <- ple4@catch.n my.stock@catch.n[my.stock@catch.n==0] <- 1 my.stock@m <- ple4@m my.control <- FLSepVPA.control(sep.age = 5) # Set up in final year my.stock@stock.n[,"2001"] <- ple4@stock.n[,"2001"] # Run SepVPA my.stock.SepVPA <- SepVPA(my.stock, my.control, fit.plusgroup=TRUE)
