[FLR-list] flash/flasher

[Iago.MOSQUEIRA at ec.europa.eu]

Hi,

FLash now compiles for Windows in R 64 bit only, and that is what is available at the repository for R 3.5.

FLasher is also 64 bit only. The main differences for the use are:

- Seasonal forecasting, needs seasonal targets.
- Separate units that differ in growth (e.g. sexes, spawning times)
- Separate ssb targets: ssb_spawn (at time of spawning), ssb_end (end of time step), and ssb_flash (FLash's trick of extending object one year if asking for ssb target when harvest.spwn = 0)
- Can project multiple stocks (FLBiols) and fisheries (FLFisheries, no metiers), still being tested fully, works with some mixfish examples.
- Includes SS3 bevholt stock-recruitment model.
- Better fwdControl() method, specially to deal with iterations in targets.
- Some small change to naming in target, val is now value, quantity is now quant.

On the TODO list for FLasher:

- Use different metrics of srp, not only ssb, on any SR model.
- This will allow use of SS3 low fecundity SRR, for example.
- Add more economic targets, only revenue is there right now.

I might be missing something, but those are the main differences I can remember now.

Cheers,


Iago

Hi, sorry if I am asking again but can you remind of the status of Flash vs. Flasher for the 64 bits version on windows.  Are both packages working now? And if yes, what are the key differences and which one is best to use?

Thanks
Clara
