[FLR-list] Missing SR relationships

[Mark Payne]

bevholtAR1 works, but not rickerAR1

> model(nsher) <- rickerAR1
> mdl <- fmle(nsher)
Error in return(FLPar(a = max(exp(res[1])), b = -max(res[2])), rho = 0) : 
  multi-argument returns are not permitted

But what is the difference between these functions and the ones that are documented in the help files?

Here's my version info FYI - its the standard install from the repo

However, it seems that there are a few missing that should be there according to the help file. ?SRModels gives me a nice list of the available models, but when I try the classic ar1 models, I get the following errors:
