[FLR-list] Initialising an FLSR

[Mark Payne]

Hi,

Cheers for the reply. I have tried that, but it doesn't actually speed it up! eg

#Without initialisation
system.time(fmle(nsher))  
 user  system elapsed 
  8.444   0.084   8.928 

#With correct initial guesses
system.time(fmle(nsher, start=params(nsher)))
  user  system elapsed 
  8.121   0.060   8.675 

But there may be something wierd with the dispatching - I get this warning to start with

> system.time(fmle(nsher, start=params(nsher)))
Note: method with signature ‘FLModel#FLPar’ chosen for function ‘fmle’,
 target signature ‘FLSR#FLPar’.
 "FLSR#ANY" would also be valid

Hi,

This should do it, use the start argument

library(FLCore)

data(nsher)

params(nsher)

out <- fmle(nsher, start=params(nsher))
