[FLR-list] ssb(stock)

harvest.spwn and m.spwn are set to NA



m.spwn(stock)  <- 0.5

harvest.spwn(stock) <- 0.5



ssb(stock)



Change 0.5 with the right value, proportion of the year (m.spwn) and fishing season (harvest.swpn) when spawning takes place.



There is a new method for FLStock, verify(), that will output a table with the results of some basic checks



> verify(stock)

           name items passes fails NAs valid

1         anyna    17     12     5   0 FALSE

2      catch.wt   741     NA    NA   4    NA

3   landings.wt   741    728    13   0 FALSE

4   discards.wt   741      0   741   0 FALSE

5      stock.wt   741    728    13   0 FALSE

6           mat   741    741     0   0  TRUE

7  harvest.spwn   741     NA    NA 741    NA

8        m.spwn   741     NA    NA 741    NA

9       harvest   741    741     0   0  TRUE

10      cohorts   352    351     1   0 FALSE

                                    rule

1                                 !anyna

2                           catch.wt > 0

3                        landings.wt > 0

4                        discards.wt > 0

5                           stock.wt > 0

6                    mat <= 1 & mat >= 0

7  harvest.spwn <= 1 & harvest.spwn >= 0

8              m.spwn <= 1 & m.spwn >= 0

9                           harvest >= 0

10                     ccohorts(stock.n)



This is telling you that, for example,



- 1. 5 slots have NAs

- 2. 4 elements in cactch.wt are NA



> sum(is.na(catch.wt(stock)))

[1] 4



Some of those NAs might be correct, but it warns you about them.



You should also look at the units of each slot



summary(stock)



and change to valid values, so you get the correct units in ssb().



- Change "tonnes" to "t"

- Change "thousands" to "1000" or "1e3"

- Set mat, harvest.spwn and m.spwn to "" (empty, as they are proprotions)





Cheers,





Iago

$discards.wt 

[1] "kg" 

 

$landings 

[1] "tonnes" 

 

$landings.n 

[1] "thousands"
